Linear and Nonlinear Functions

Linear vs. Nonlinear

Functions

Multiple Select

To determine if a relation in a table is a linear function, I need to

• Use the vertical line test.

• Check $$\frac{\Delta y}{\Delta x}$$

  This rate of change must be the same.

• Look for the y-intercept.

• Look for the initial value.

Multiple Choice

Is this table showing a linear or nonlinear function?

• Linear, the slope is constant

• Nonlinear, the slope is not constant
