Open Ended

A graph is shown. How do you determine if this is a function or not?

​

​

Multiple Choice

Two functions are shown. Which function has the greater rate of change?

• y = 5x + 4

Multiple Choice

Two functions are shown. Which function has the greater initial value?

• y = 5x + 4

Open Ended

Create an equation for a third function that has a greater rate of change than one function but a smaller initial value than the other function.

Multiple Select

Several functions represent different savings account plans. Which functions are nonlinear?

• y = 5.50x + 7

• $$y\ =\ 5.5\left(1.02\right)^x$$  

• y = 0.5(x)²

• y = 7.5x

• y = 7.25 + x²

Multiple Choice

The function y = 3.50x + 2 represents the total amount of money, y, saved over x weeks. What is true about the function?

• It is linear because it is always increasing

• It is linear because it increases at a constant rate

• It is nonlinear because it is always increasing

• It is nonlinear because it increases at a constant rate

Multiple Choice

Kayden creates a linear function where x is the input and y is the output, and m and b are constants. Which equation could represent Kayden's function?

• $$y\ =\ \frac{1}{x}+mb$$  

• y = mx + b

• $$y\ =\ my\ \cdot\ by$$  

Multiple Choice

Which statement about the graph of Kayden's function is true for all values of m and b?

• The graph is increasing

• The graph is decreasing

• The graph goes through the origin

• The graph has a constant rate of change

Open Ended

The cost, C, to rent a car for d days is shown in the table. Write an equation that represents this function.

Fill in the Blanks

Using the table, create an equation to represent hte linear model that Suzie's plumbing uses to determine total cost, C, in terms of hours worked, h.

Multiple Choice

Which graph represents a linear function increasing at a constant rate?

Kim rides a stationary bike for fifteen minutes of exercise. Kim starts her ride slowly, stops for 2 minutes, and then continues her ride faster than she started.

​

Multiple Select

Mary and Kim go bike riding on some trails. Graphs of the functions representing one of their rides are shown, where 𝑥 is the time, in minutes, and 𝑦 is the distance, in miles.

Select all statements that are true based on the graphs shown.

• Kim stops for 3 minutes

• Mary stops for 2 minutes

• Mary slows down after minute 8

• Kim and Mary both ride the same distance at 15 minutes

• Mary and Kim both begin the bike ride at the same speed between minutes 0 and 4.

Multiple Select

Mary and Kim each take 15 minutes to ride their bikes to school. The graphs of the functions that model their rides are shown, where x is the time, and y is the distance, in miles.

Use the graphs to select the true statements.

• Kim rode her bike the fastest in interval A, as compared to the rest of her ride

• Mary stopped for an interval of time

• Mary rode slower in interval C than in interval B

• Mary and Kim both live 0.7 miles from school
