Question

If f(x)=(x1)2(x+1)2, then the function f has 
  1. a local maximum at x=15
  2. a local minimum at x=15
  3. a local minimum at x=1
  4. a local maximum at x=1


Solution

The correct option is A a local maximum at x=15
f(x)=(x1)2(x+1)3
f(x)=2(x1)(x+1)3+3(x+1)2(x1)2=0(x1)(x+1)2(5x1)=0x=1,15,1
f(x) has local maxima at 15
