15) Consider the function defined by f(x) = -5x2 +24x -16 over the interval [1, 2] . a) Find the right-hand Riemann Sum using n sub-intervals of equal width. Completely simplify your answer. Your final answer should be in terms of n with no sigma notation. b) Use your answer in part (a) above to calculate the right-hand Riemann sum for n = 10.:) Find the left-hand Riemann Sum using n sub-intervals of equal width. Completely simplify your answer. Your final answer should be in terms of n with no sigma notation. d) Use your answer from part (c) to calculate the left-hand Riemann sum for n = 10, @) Now use the Fundamental Theorem to calculate J."-5x] + 24x - 16 dx .
