Answer:

Step-by-step explanation:

The first thing to do is get a graph of the function if you can.

The graph helps you see the following.

  1. The critical points are at +/- 3
  2. The graph is increasing from -∞ ≤x<-3 Watch that you do not include - 3
  3. The graph is increasing form -3<x<0
  4. The graph is decreasing from 0<x<3
  5. The graph is decreasing from 3<x<∞

Answer:

Increasing:  on the interval of x: (-∞, 0)

Decreasing: on the interval of x: (0, ∞)

Step-by-step explanation:

See attached photos, one is done using calculus, the other is done using the graph.  (I'm not sure which level of math you are in)

*For the graph, you can see that f(x) is always increasing from  (-∞, 0), and always decreasing from (0, ∞)
