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.

Identify the y-intercept of the function.

• (-2, 5) 

A function is a type of rule in which each ​ (a)   results in exactly one ​ (b)   .​
