The graph is a picture of both ​ (a)  

• relation

• function

• domain

• range

• x-intercept

• y-intercept

• rate of change

• minimum

• maximum

• extrema

Answer explanation

Extrema are both the highest (maximum) point and the lowest (minimum) points.

What is the definition of function?

• Has inputs and outputs

• Every input has only one output

• Inputs have different outputs every time

• x-values and y-values
