Question

On what intervals is the function increasing?

Indicate intervals on the x-axis using the Ray tool for intervals that extend to infinity and the Segment tool for bounded intervals.

Graph a ray by selecting the endpoint followed by a point on the ray. Graph a segment by selecting an endpoint followed by the other endpoint.

Answer 1

Answer:

• [-7, - 2] and [3, 7]

--------------------------------------

The graph has two local maximums and two local minimums.

The intervals between those points are the increasing intervals.

Refer to the attached, where the intervals are marked.

The intervals are

• x = [-7, - 2] and [3, 7]
