Determine the extreme values of each function on the given interval.
a) f(x)= 1 + (x+3)^2 , -2<=x<=6
This is my work:
Critical numbers of f'(x)=2(x+3)
1) f'(x)=0 when x=-3
Test Critical numbers & end points
Abs max is 82 (this answer is correct with the back of the book)
Abs min is 2 (this answer is WRONG with the back of the book)
What did I do here that is wrong?
Would the local max be 82 at x=6 and the local min be 2 at x=-2?
