You are given the four points in the plane A=(7,4) ,B=(9,3) ,C=(13,5) , and D=(16,2 . The graph of the function consists of the three line segmentsAB ,BC and CD . Find the integral between x= 16 and x= 7 by interpreting the integral in terms of sums and/or differences of areas of elementary figures. Please HELP!

you find the area of each of the segments your answer would be 19/5
