Do the following. a = 16(a) Use six rectangles to find estimates of each type for the area under the given graph of f from x = 0 to x = 48.(i) Sample points are left endpoints.L6 = 1(ii) Sample points are right endpoints.R6 = 2(iii) Sample points are midpoints.M6 = 3I don't know how to get to the answer. Could you show your work? That would be more helpful than the answer.
