Your instructor may ask you to turn in this graph.) Then use a geometric formula to evaluate the integral. so here what i did was separate(1/ and the x so i graphed y=x and then i got that at point 5, y =5 so then i found the area of the triangle (5)(5)(.5)= 12.5 the multiply by the (1/ so i got 1.5625 or 25/16 is this correct?
