Comparing Linear and Nonlinear Functions

What is the rate of change in a linear function commonly referred to as?

• Variable

• Y-intercept

• Slope

• Constant

If the y-intercept of a function is 1, what does this indicate?

• The function has no initial value

• The function starts at y = 1 when x = 0

• The function is nonlinear

• The function has a slope of 1

• $24

• $30

• $240

• $290

Whose musical instrument costs more initially?

• Neither

• Both cost the same

• Samantha's

• Felipe's

Which function has a greater rate of change if Function A has a slope of 1 and Function B has a slope of 1.5?

• Cannot be determined

• Both have the same rate of change

• Function B

• Function A

What is the y-intercept of Function A if it starts at (0, 4)?

• 1

• 0

• 3

• 4

How can you identify a nonlinear function from its graph?

• It has a constant rate of change

• It starts at the origin

• It is a straight line

• It is a curved line

What indicates a linear function in a table of values?

• A curved pattern

• A constant rate of change

• A variable rate of change

• A starting value of zero

If Justin saves $2 every week, what type of function does this represent?

• Nonlinear

• Linear

• Exponential

• Quadratic

Which function has the greatest rate of change if one has a slope of 4, another has a slope of 5, and the third has a negative slope?

• All have the same rate of change

• The function with a negative slope

• The function with a slope of 5

• The function with a slope of 4
