when f ' is positive then the funtion f(x) is increasing

for [-2, -1] and [2, +infinity) << these are increasing intervals

when f ' is negative the function is decreasing

for (-infinity, -2] and [-1, 2] the function is decreasing

There is no gradation so estimating.....

f'(x) is increasing for -3<x<-1.5 and 1<x<3

f'(x) is decreasing for -1.5<x<1
