Graph the function f(x) over the given interval. Partition the interval into 4 subintervals of equal length. Then add to 4 your sketch the rectangles associated with the Riemann sum f(ck) Axk, using the indicated point in the kth subinterval for ck. k=1 8) f(x) = x-2, [0, 8], left-hand endpoint 64- 60+ 56+ 52- 48 44+ 40+ 36- 32- 28- 24 12- 8- + + 2 4 6 8 x
