25-32. Left and right Riemann sums Complete the following steps for the given function, interval, and value of n. a. Sketch the graph of the function on the given interval. b. Calculate Ax and the grid points x, x1,.. Xn c. Illustrate the left and right Riemann sums. Then determine which Riemann sum underestimates and which sum overestimates the ar under the curve. d. Calculate the left and right Riemann sums. 25. f(x) = x + 1 on [0,4]; n = 4 26. f(x) = 9x on [3, 8]; n = 5 T27. f(x) = cos x on 0, 28. f(x) = sin x-3 TT 2 ; n = 4 on [0,3]; n = 6 29. f(x) = x - 1 on [2, 4]; n = 4 30. f(x) = 2x on [1, 6]; n = 5 T31. f(x) = x/2 on [1, 4]; n = 6 T32. f(x) = In 4x on [1, 3]; n = 5 25-32.
