Graph 2x - 4 = y

• A

• B

• C

• D

Identify the range of the following function when given the domain { 2, 3, 10}:
y = 4x - 12

• 4, 12, 20

• -20, 0, 28

• -4, 0, 28

• 8, 12, 40

Describe the function.

y = 3x + 12

• Nonlinear function. The graph will not be a straight line

• Nonlinear function. The graph will be a straight line

• linear function. The graph will not be a straight line

• linear function. The graph will be a straight line

Which equation matches the grpah? Use a graphing calc!

• x + y = 0

• 5x + 6y = 12

• 3x + 2y = 5

• 4x + 4y = 4

How do you know if a graph shows a function?

• Horizontal Line test (must pass through once)

• Horizontal Line test (must pass through more than once)

• Vertical Line test (must pass through once)

• Vertical Line test (must pass through more than once)
