1. Graph the function over the specified interval. Then use simple area formula from geometry to find the area function A(x) that gives the area between the graph of the specified function f and the interval [a, x]. Confirm that A'(x) = f(x). Also, verify your answer by direct integration. a. f(x) = 6-x; [a,x] = [-2, x]
