Question

At what point to the increasing decreasing part of the graph in part a intersect?

Answer 1

(-1, 3)

Explanation:

From the picture attached,

There are two lines showing increasing and decreasing trends.

Line passing through hollow point is the increasing part and another line passing through a solid point is showing the decreasing part of the graph.

Point of intersection of these parts or common point where these segments join is point (-1, 3).

Therefore, (-1, 3) is the answer.
