8. Suppose that f is twice differentiable with continuous second derivative (that is, both f and f' are differentiable and f" is continuous). The following table gives some values of f and f'. I -1 0 1 2 e 3 5 e2 f(x) 3 -1 7 1 5 e2 5 0 f'(x) 1 3 4 2 0 5 11 03 Use the table above to compute the following. If there isn't enough information to solve the problem, write "Not Enough Info". (a) 15 pts] dr f'(x) f(x) (b) [5 pts] xf" (x) dx
