You are given the four points in the plane A = (2,7), B = (7, −5), C = (11,2), and D = (13,-5). The graph of the function f(x) consists of the three line segments AB, BC and CD. Find the integral 13 f(x) da by interpreting the integral in terms of sums and/or differences of areas of elementary figures. 2 13 [1³ f(x) dx = You are given the four points in the plane A = (2,7), B = (7, −5), C = (11,2), and D = (13,-5).
