Answer

Explanation:

Step1: Identify key - point

The vertex of the parabola is at $x = - 3$.

Step2: Determine increasing interval

For a parabola opening upwards, the function is increasing to the right of the vertex. So the increasing interval is $(-3,\infty)$.

Step3: Determine decreasing interval

The function is decreasing to the left of the vertex. So the decreasing interval is $(-\infty,-3)$.

Answer:

Increasing intervals: $(-3,\infty)$ Decreasing intervals: $(-\infty,-3)$
