C!) (8.) Consider the accumulation function A(a:) = f 33 ds. 0 Using the fact that A'(:c) = 2:3, obtain a formula that expresses A in terms of 1:. (b) We now modify A so that accumulation begins at the value :1: = 1 instead of :1: = 0 as in part (a). This results in A(:c) = f: 33 (13. It is still true that A' (m) = 3:3, but now A( 1) = 0. Obtain a formula that expresses this modied A in terms of 2:. How do the formulas for A in parts (a) and (b) differ? 6. Accumulation functions and their derivatives. Let f(x) = 2 + r on the interval 0
