The graph of f consists of the three line segments shown. Let 9 be an accumulation/area function dened by 9(x) = f f(t) dt. 0 (a) Evaluate the following: i. 9(0) iii. 9(2) v. 9'(2.5) vii. 9\"(2.5) ii. 9(1) iv. 9(4) vi. 9'(4) viii. 9\"(4) (b) Where is 9 increasing? Where is 9 decreasing? (c) Identify and classify the local extreme points (if any) of the function 9. ((1) Where is 9 concave up? Where is 9 concave down? 4 (e) TRUE or FALSE: / f(:c) d2: = 9(4) 9(0). 0 (f) TRUE or FALSE: The function 9 is an antiderivative of f
