Hi, I found A'(-2) to be 1. However, I'm stuck on part B of this question. How do I find the A''(-2) part on the graph? Also, would Part C be "decreasing?" How do I show this? Thank you in advance.

The graph below represents the function y = f(t). 8 6 -3 -2 -1 N Let A(x) = f (t ) dt. 3 Use the graph to answer the following questions: a) Evaluate A' ( - 2) = b) Evaluate A"' ( - 2) = c) Is A(x) increasing or decreasing at r = 0.5? O decreasing O increasing
