I need solve this assignment of MA 166

Work Problem 1 (20 points) Estimate the area under the graph of f(x) = Vx + 4 from a = 0 to b = 2 by using n = 4 rectangles of equal length and by using a) right endpoints, b) left endpoints. Work Problem 2 (20 points) For the function f(x) =6 - 6x2 + 8x consider the definite integral So f(x) dx. a) Evaluate this integral. b) Find a value of N for which the integral becomes zero. Justify your answer. Work Problem 3 (20 points) For the function f ( ac) = 2 consider the integral SY f(x) dx. a) Use the midpoint rule with n = 4 to estimate this integral. b) Use the Fundamental Theorem of Calculus Part Two to find the exact value of the integral
