looks like F(x) has a max at x = 50
estimate the area under the curve from x = 20 to x = 50, then add to F(20)
[IMG]file:///C:/DOCUME%7E1/ADMINI%7E1/LOCALS%7E1/Temp/moz-screenshot.jpg[/IMG]The graph of the derivative F ' of some function F is given in the figure below.
If F(20) = 365, estimate the maximum value attained by F. Your answer should be within 20 units of the correct value.
