You are given the four points in the plane A=(2, 4), B=(−4, 6), C=(7, 8), and D=(9, 1). The graph of the function f(x) consists of the three line segments AB, BC and CD. Find the integral
9
∫ f(x)dx
2
by interpreting the integral in terms of sums of areas of elementary figures.

draw the trinangle on a graph, and split the trinangles into parts.
since it's form 2-9 along the x-axis, you should be able to find a slope function in a form of y=ax+b
it's easy
