Use simple area formulas from geometry to find the area function A(x) that gives the area between the graph of the function (x) = 6x + 6 and the interval [0, x]. Confirm that A'(x) = f(x). A(x) = Use simple area formulas from geometry to find the area function A(x) that gives the area between the graph of the function f(x) = 17x 17 and the interval [2, x]. Confirm that A'(x) = f(x). NOTE: Enter the exact answer. A(x) -
