Calculate the indicated Riemann sum S5, for the function f(x)=174x2. Partition [2,8] into five subintervals of equallength, and for each subinterval xk1,xk, let ck=xk1+xk/2.

Calculate the indicated Riemann sum S, for the function f(x) = 17 -4x . Partition [ - 2,8] into five subintervals of equal length, and for each subinterval [Xk - 1,XK ], let ck = (Xk - 1 + XK ) / 2. S, =
