A certain function must be integrated for Put and note that on and the integral is
The point of intersection for x would be 4 so my bounds would be 0 and 4 since the absolute value makes one bound 0. Then I subtract the two, sincd 2x is the upper It'd be 2x-(x^2-8) which becomes 2x-x^2+8 and after integration it would be 2x^2/2-x^3/x+8x. I plug in four and get 80/3 every time. Where am I going wrong?
