1. Fundamental theorem, Graph!!

The graph of the derivative F ' of some function F is given in the figure below.

If F(20) = 280, estimate the maximum value attained by F. Your answer should be within 20 units of the correct value.

this is the last one i need help with, thanks

This function has a max at x=50...look it crosses the x-axis and by the second derivative test its slope is negative..i.e its a max
