The picture ​ (a)   a function because every ​x ​ (b)   point to exactly one y.

• shows

• does not show

• does

• does not

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.
