Step 1

We use a graphing calculator to graph h(x)

Step 2

The x-intercepts are at x=-1, x=0 and x=1

Those are the critical points of f(x).

When h(x) is negative then f(x) will be decreasing and when h(x) is positive then f(x) will be increasing.

h(x) is negative in (-infinity,-1) and (0,1)

So, in (-infinity,-1) and (0,1) f(x) is decr...
