Use this graph of y = f(x) and the fact that / f(x)dx = 3 4 3 4 5 5 7 8 9 10 17 12 13 14 15 16 17 12 A to compute the following: a. ( f(z) da = b . [ f(z ) da = c. Use the graph to find the Right-endpoint Riemann sum for f(x) on the interval [0, 8] with the partition P = {0, 1, 4, 6, 8}: E f(CK) . AIK = k =1 d. If the function, y = f() graphed above represents flow rate of water in gallons per minute where r is in minutes, write a sentence to interpret in context the value of your answer in part a
