Calculate where a and b are the left and right end points f

Calculate , where a and b are the left and right end points for which f is defined, by using the interval additive property and the appropriate area formulas from plane geometry. Begin by graphing the given function.

Solution

=₀¹5xdx+₁⁵5dx+₅¹³xdx

=5/2+5*4+(13^2-5^2)/2

=94.5
