Question

Determine the intervals on which the function is increasing, decreasing, or constant.

Answer 1

hello: by graph
answer : 1

Answer 2

Increasing on (-4, 2) and (1, 3); Decreasing on (-2, 1).

Explanation:

The function is said to be increasing function if as the value of x increases, then the value y also increases.

The function as a decreasing function if as the value of x increases, y decreases or vice-versa.

And the function is said to be constant if as x increases the value of y remains the same or vice-versa.

Here, Function is increasing from (-4, -4) to (-2, 4.5) and from (1, 0) to (2, 8)

and function is decreasing from (-2, 4.5) to (1, 0).
