Question 5 (1 point) Consider a function f with the following table of values: "mu ----n-- Approximate I26 f(ac)d;13 using a Riemann sum with two rectangles of equal width and midpoints. Question 6 (1 point) The graph of y = f(t) is given below: N 0 4 The definite integral f(t) dt equals (Your answer should be a number.)Question 7 (1 point) Suppose (3f(x) ) dac = 12 and 2 5 f(x)dx = 2. Compute f(x) dac. 5 2 Oo O 10 0 4 0 2Question 9 (1 point) Let f(x) be a function which is continuous for all x. Let L100, R100 and M100 be the Riemann sums using 100 subintervals with left, right and middle sample points, respectively, for f on the interval [0, 1]. Which of the following statements is FALSE? If f is decreasing on [0, 1], then L100 2 M100 All three sums L100, R100, M100 exist. If f is decreasing on [0, 1/2) and increasing on (1/2, 1], then L100 = M100. The definite integral So f(x ) da exists (i.e. f is Riemann integrable on [0, 1]). If f is increasing on [0, 1], then L100
