Answer:

  increasing: (-∞, -5) and (-2, ∞)

  decreasing: (-5, -2)

Step-by-step explanation:

You want to know the intervals of increase and decrease for the cubic relation that has a relative maximum at (-5, 8) and a relative minimum at (-2, 5).

Increasing

A function is "increasing" when y values increase as x-values increase. The graph has positive slope, extending upward to the right.

The graph goes up to a relative maximum, so is always increasing on the interval to the left of a relative maximum.

The graph goes up from a relative minimum, so is always increasing to the right of a relative minimum.

A turning point is not included in the "increasing" interval, because the slope is 0 there (not positive).

Decreasing

A function is "decreasing" when y values decrease as x-values increase. The graph has negative slope, extending downward to the right.

The graph goes down to a relative minimum, so is always decreasing to the left of a relative minimum.

The graph goes down from a relative maximum, so is always decreasing on the interval to the right of a relative maximum.

A turning point is not included in the "decreasing" interval, because the slope is 0 there (not negative).
