  1. Approximate the area under f(x) = (x – 2, above the x-axis, on [2,4] with n = 4 rectangles using the (a) left endpoint, (b) right endpoint and (c) trapezoidal rule (i.e. the “average” shortcut). Be sure to include endpoint values and write summation notation for (a) and (b). Also, on (c), state whether the answer over- or underestimates the exact area and why.
