WebMorevoer, since f' (x)<0 in (-infinity, 1) u (3,5), we see that f is decreasing in (-infinity, 1) u (3,5). Example 2: Suppose f' (x) = - (x-1) (x-3) (x-7) , then f' (x)>0 in (-infinity, 1) u (3,7) and hence f is increasing in those intervals. On the other hand, f' (x)<0 in (1,3) union (7, infinity), so f is decreasing there.
