use the graph to determine the following a find the numbers

use the graph to determine the following
a. find the numbers at which f has a relative maximum. What ate these relative maxima?
b.find the numbers at which f has a relative minimum. What are the relative minimum?

a. the number(s) at which f has a relative maximum is/are (integer or decimal)

the relative maximum/maxima is/are

b. the number(s) at which f has a relative minimum is/are

the relative minimum/minima is/are

Solution

(a) only one relative maximum

The relative maximum at x=-1

And relative maximum is 4

(b)two relative minimum exist

The relative minimum at x=-2 is 0

And the relative minimum at x=0 is 0
