For this problem, you will need to use the Desmos Riemann Sum Calculator. (This link opens a new tab/window.) Initially, the calculator shows a left Riemann sum with n= 5 subintervals for the function f(x) = 2x +1 on the interval [1,4]. Update the applet to consider the function f(x) = x2 +1 on the same interval. Compute the following Riemann sums. Ls , Ms L25 M25 • R2 L100= M100 R100 Observe any patterns you see in the calculations above, and make an educated guess of the exact area bounded by f(x) = *? + 1 and the x-axis on the interval (1,4). Exact Area =
