If f^(prime)x=g(x)(x-a)^2,w h e r eg(a)!...

If `f^(prime)x=g(x)(x-a)^2,w h e r eg(a)!=0,a n dg` is continuous at `x=a ,` then `f` is increasing in the neighbourhood of `a` if `g(a)>0` `f` is increasing in the neighbourhood of `a` if `g(a)<0` `f` is decreasing in the neighbourhood of `a` if `g(a)>0` `f` is decreasing in the neighbourhood of `a` if `g(a)<0`
