​The independent variable represents the input and the dependent variable represents the output because the output value depends on what the input values are.

​Create a function table for y = 4x − 1. Use the input values −2, 0, 2, and 4.

​Domain: {-2, 0, 2, 4}
Range: {-9, -1, 7, 15}

Match

Complete the function table for y = −4x − 3.

• x = -1

• x = 1

• x = 3

• x = 5

y = 1

y = -7

y = -15

y = -23

• y = 1

• y = -7

• y = -15

• y = -23

An online photo printing service charges $0.15 per photo and $2.99 for shipping. The total cost c for printing and shipping any number of photos p can be represented by the function c = 0.15p + 2.99.

Match the inputs to their corresponding outputs.

• p = 1

• p = 2

• p = 3

• p = 4

c = 3.14

c = 3.29

c = 3.44

c = 3.59

• c = 3.14

• c = 3.29

• c = 3.44

• c = 3.59
