1. Consider the function () = 5 − 43 + 4 + 4 over the interval [−1, 0]. a) Determine the right-hand Riemann sum. Will this be an overestimate or an underestimate? ` b) Determine the left-hand Riemann sum. Will this be an overestimate or an underestimate? c) Determine the midpoint Riemann sum. Will this be an overestimate or an underestimate? d)Calculate∫0 (5 −43 +4+4) −1 e) Calculate the error between the integral and the Riemann sums calculated in steps a–c.
