Linear and Functions

• Function
• Not a Function

Is the function linear or nonlinear?

• Linear Function

• Nonlinear Function

What is the slope?

• 1

• 1/2

• 2/1

• -2

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)

Check the correct answers: In order to be a linear function:

• It's graph must have a straight line

• It must pass a polygraph test

• Each x-value has only one y-value

• A parabola is a Linear Function

Is function represented by the table linear or nonlinear?

• linear

• nonlinear

Find the rate of change

• 1

• 2

• 11

• Not a constant slope/Non-Linear

Slope is another word for:

• Initial Value

• Rate of Change

• Change in Y's

• Y-intercept

What is the definition of a function?

• Has inputs and outputs

• Every input has only ONE output

• Inputs have different outputs every time

• x-values and y-values

What is the rate of change?

• 7

• 4
