## Homework Statement

The problem is in the attached file. The part I need a little help with is part b.

## Homework Equations

and attempt at a solution[/B]For part a, I got h(8) = 2, h'(6) = -2, and h''(4) = -2.

For part c, I found that the integral from 0 to 5 is 7, so I multiplied 7 by 7 to get 49 (because 35 = 5*7). And f(5) = 0, so f(108) also equals 0. I got the tangent line y - 49 = 0(x - 35).

For part b, I think we're supposed to consider x = 0 and x = 3, since this is where the graph starts increasing from decreasing and vice versa. But I also think we have to evaluate the integral at these points. Can someone explain this?
