This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part. For the function, do the following. f(x) = 6x from a = 2 to b = 3 Exercise (a) Approximate the area under the curve from a to b by calculating a Riemann sum using 5 rectangles. Use the method described in this example. Step 1 The sum of the areas of the rectangles approximates the area under the curve, though not very well. We begin by sketching f(x) = 6x, a line through the origin with slope 6, so that we can draw the rectangles and find their total area. To find the widths of the rectangles, we find the length of the interval from a = 2 to b = 3 and divide it by the number of rectangles we want. Thus, our rectangles have bases of length Ax = D - a The left-hand endpoints (the ones that we will use for the rectangle heights) are 2, 2.2, 2.4, and 2.8
