Functions (7th after 6.4)

Is this function linear or nonlinear?

• linear
• nonlinear

Is this function linear or nonlinear?

• linear

• nonlinear

Why is this function nonlinear?

• This is a nonlinear function because it is on the side.
• This is a nonlinear function because it is a straight line.
• This is a nonlinear function because the line is curved.
• This is a nonlinear function because it is open ended

Why is this function linear?

• This is a linear function because it does not have a constant rate of change
• This is a linear function because it creates a curved line.
• This is a linear function because it have a constant rate of change.
• This is a linear function because it's y-intercept is (0,2)

• This is a linear function because it has a constant rate of change.
• This is a linear function because it does not have a constant rate of change.
• This is a linear function because the slope is -1

Which equation represents a linear function?

• y=8x

• x=5

• y=4x²

• y=x³

Which answer choice is true?

• The table represents a linear function because there is a pattern for the x-coordinates and y-coordinates.
• The table represents a linear function because the ratio of the change in the y value and the change in the x value is constant.
• The table represents a nonlinear function because the ratio of the change in the y value and the change in the x value is not constant.
• The table does not represent a function because there is more than one output for at least one input.
