So I have this question:

After screen-shotting it I realized I added instead of subtracting, so my answer to the first part is about 4.7...is that right?

The second part I'm not sure at all how to find the equation for the derivative of the curve.. when I don't have the equations for h(x), how would I find the derivative equation? I do know that you put (5/2) in for x once you have the equation.

Also, the x value that gives the maximum h(x) would have to be 4 right?

Any help would be great!
