Let f"(2) = 26- 424 + 2+1 Find f(x).\f\f(a) Evaluate the Riemann sum for f(z) = 5z% 2z, taking the sample points to be right endpoints and a=0,b=4 and n =2 4 f 522 2zdx 0 (b) Evaluate using your result from the previous part. Then, verify your answer is correct by calculating the value of the integral using another method. Determine the area of the region bounded by x = 3 + y2, x = 2 - y, y = 1, y = -2.\f
