Comparing Properties of Two Functions Worksheets
In math we use functions to model situations or phenomena that is consistent. While there may be some limits to the level of accuracy that be exhibited, they are very help for understanding a scenario and predicting changes that can be made to improve an outcome. There will be times when you have multiple options of how you can use a function and analyzing and comparing those possible uses of functions can indicate which would be best for our situation. We lean heavily on the use of graphs to understand the nature of functions, but they are not always practical solutions. In this section we will focus on analyzing function tables and algebraic comparisons. These worksheets and lessons teach students how to compare the various properties of functions.

How to Compare the Properties of Two Functions
A function is a mathematical relationship that takes in an input and based on the rule that is assigned will produce an output. They are a concept which needs to be adequately understood so that it doesn't create problems in the future. Most students might not know that this concept will get more difficult as you move to higher classes. Functions can be represented in many different ways. The most common ways to illustrate them is through the use of an input-output table, equation, or graph. There are three ways to compare the math relationships, i.e., algebraically, numerically, and graphically.
Let us compare two functions numerically. Let us consider an example of y = 3x + 5. In this example, y is a dependent of x, so in other words, if we keep on changing the value of x, then y will increase as well. Let's look at the table as an example.
x, y = (-1, 2), (0, 5), (4, 17), (-5, -10)
Comparing functions graphically is probably the easiest to understand. You cannot always use this method because sometimes the inputs and outputs simply do not fit neatly on a coordinate plane. We compared the graph of two functions below:
![lesson 5 problem solving practice compare properties of functions Graphs of Functions](https://www.mathworksheetsland.com/13comp2funct/1.png)
Can you spot any significant trends? Starting with the function represented by the blue line, we can clearly see that as the value of x increases, the value of y decreases. The function represented by the green line, on the other hand, has a much different trend. As the value of x increases, on the green line, so does the value of y. Graphs like this help us understand the nature of functions and make solid predictions of them.

The table and the equation provided represent two different functions. Which of these two functions—either table or equation form—has the greater rate of change, and what is the rate of change?
![lesson 5 problem solving practice compare properties of functions Screen shot 2016 03 14 at 8.52.05 am](https://vt-vtwa-assets.varsitytutors.com/vt-vtwa/uploads/problem_question_image/image/34846/Screen_Shot_2016-03-14_at_8.52.05_AM.png)
The rate of change is also known as the slope. As we have learned we can use the following equation to solve for the slope of the table:
An input/output table displays sets of ordered pairs. The input column represents the x-values and the output column represents the y-values. We can select two sets of ordered pairs from the table to solve for the slope:
In order to determine the slope of the equation, we need to make sure the equation is in slope-intercept form:

Sam wants to take his music player and his video game player on a car trip. An hour before they plan to leave, he realized that he forgot to charge the batteries last night. At that point, he plugged in both devices so they can charge as long as possible before they leave.
Sam knows that his music player has 40% of its battery life left and that the battery charges by an additional 12 percentage points every 15 minutes.
His video game player is new, so Sam doesn’t know how fast it is charging but he recorded the battery charge for the first 30 minutes after he plugged it in.
a. If Sam’s family leaves as planned, what percent of the battery will be charged for each of the two devices when they leave?
b. How much time would Sam need to charge the battery 100% on both devices?

Function A is shown in the table below.
Four more functions are represented below. Find:
- a function that is the same as Function A
- a function with the same rate of change as Function A but with a different initial value
- a function with the same initial value as Function A but with a different rate of change
- a function with a greater rate of change than Function A
Student Response
An example response to the Target Task at the level of detail expected of the students.
The following resources include problems and activities aligned to the objective of the lesson that can be used for additional practice or to create your own problem set.
- Have students represent functions in four ways (tables, equations, graphs, verbal descriptions). If students use notecards to represent the functions, then they can use the notecards in various ways. For example, students could form groups and play Memory with the note cards, turning them over and finding matching pairs. Or, students could make comparisons between the notecards based on rate of change or initial value. The goal of these activities is to enable students to see functions in various representations and to compare across those representations.

7th & 8th Grade Math - Comparing Linear Functions
In fall of 2008, Sally Keyes (math coach), Kamaljit Sangha (7/8 math teacher/department leader) and Cecilio Dimas (7/8 math teacher) developed our first lesson on cost-analysis. By the end of fall 2008, all eleven 7th grade classes, regular and accelerated, had been taught the DVD Plan lesson. The foundation of this lesson is constructing, communicating, and evaluating student-generated tables while making comparisons between three different financial plans. Students had been given three different DVD rental plans and asked to analyze each one to see if they could determine when the 3 different DVD plans cost the same amount of money, if ever. Using this idea as an anchor problem taken from our original pre-assessment with the MARS task "Gym," we were devising avenues for our students to explore and understand specific multiple representations of breaking points. We believe that being able to understand multiple representations for the breaking even points in a written explanation, a table, a graph, and an algebraic rule is critical to success in algebra. The design of our year-long lesson study is to address each of these multiple representations: verbal, tabular, graphical, and algebraic generalization. Our perception is that students tend to see the graph as the “last thing” with no real connection to the mathematics of the situation or to other representations and that was our reason to put it after the verbal and tabular representations. Lesson Goals -Comparisons of different deals: do these representations make mathematical sense and do they match the mathematics of the three plans? -Verbal descriptions -Tables graphs -Algebraic rules
