100 4.3. THE DEFINITE INTEGRALFigure 4.7: A left Riemann sum with 5 subintervals for the function f(x) = 2x + 1 on the interval[1, 4]. The value of the sum is L 5 = 16.2.1” for the function formula). Use the applet to compute L n , M n , R n for n = 10, n = 100,and n = 1000. What do you conjecture is the exact area bounded by f(x) = x 2 + 1 and thex-axis on [1, 4]?(e) Why can we not compute the exact value of the area bounded by f(x) = x 2 + 1 and thex-axis on [1, 4] using a formula like we did in (b)?⊲⊳
