7. (15 pts) Numerical Integration. Given a continuous function f (x) on the interval [a, b], write the Lagrange form of the quadratic polynomial interpolating f(a), (a b)), f(b). Instead of calculating the integral I(f) Jaf(x)dx we could approximate it via Q(f) = | q(x)dx. Find an expression for this quadrature rule, the so-called Simpson's rule.

A function f, which has derivatives for all orders for all real numbers, has a 3rd degree Taylor polynomial for f centered at x = 5. The 4th derivative of f satisfies the inequality f^(4)(x) ≤ 6 for all x the interval from 4.5 to 5 inclusive. Find the LaGrange error bound if the 3rd degree Taylor polynomial is used to estimate f(4.5). You must show your work but do not need to evaluate the remainder expression.
