Identify where the function is increasing and where it is decreasing.

• increasing x > -1 and decreasing x<-1

• increasing x < -1 and decreasing x > -1

• increasing ꓣ and decreasing nowhere

• increasing -1 < x < 4 and decreasing -3 < x < 1

Which coordinate is a relative maximum for the graph?

• None

• (0,4)

• (3,1)

• (1, -1)

Identify the y-intercept(s) of the function.

• None

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.
