Question

If I choose to integrate this, how would it be done? And how come you did not integrate the function instead of adding values to calculate the area on the graph?  When I did the integral of the function,  did not get the same answer.
Using F(x) = ( 2x - 1/2(3.14)x^2) dx for the interval between 1 and 3. 
See attached - part b.   Thanks for your help.
