(8 pts) Given that S, f(x)dx = -5, JP g(x)dx = 9, f5 f(x)dx = 2, and Jr g(x)dx = 3, evaluate Ss (2f(x) -9g(x))dx. Show ALL steps for full credit. (8 pts) The graph of f (x) =1+x, xe[-1,2] is given. Approximate the net area bounded by the graph of fand the x-axis from x = -1 to x = 2 using a left Riemann sum with n = 6. Show your work. Also sketch and shade the approximationg rectangles. y .4 3 +2 N -1 N -1
