7. {10pts} Consider f(x) = Sim: (a) On the graph below, draw the rectangles corresponding to a left Riemann sum with n = 8 subintervals of equal width on the interval [0.21:].Your drawing should be clear and easy to read. (b) Using the rectangles vou drew on partial, estimate the area for the function on the interval [0,11]. Show all work
