a. Use Simpson’s Rule to approximateГ- х3 dx Jo using two subintervals (n = 2); compare the approximation to the value of the integral.

b. Use Simpson’s Rule to approximatex³ dx using four subintervals 1n = 42; compare the approximation to the value of the integral.

c. Use the error bound associated with Simpson’s Rule given in Theorem 7.2 to explain why the approximations in parts (a) and (b) give the exact value of the integral.

d. Use Theorem 7.2 to explain why a Simpson’s Rule approximation using any (even) number of subintervals gives the exact value ofwhere f(x) is a polynomial of degree 3 or less.
