If you graph the function f for 0 is less than or equal to x which is less than or equal to 3, which of these has the least value and why? It's not E :)

3 (A) f(x) da 3 (B) Left Riemann sum approximation of f(x) dx with 4 subintervals of equal length 3 (C) Right Riemann sum approximation of f (2) da with 4 subintervals of equal length Co (D) Midpoint Riemann sum approximation of / f(x) dx with 4 subintervals of equal length (E) Trapezoidal sum approximation of / f(x) dx with 4 subintervals of equal length V
