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.
Verify by direct integration that the functions are orthogonal with respect to the indicated weight function w(x) on the given interval. 4p(x) = 1, 4,6x) = -x + 1, 12(X) = 2*2 - 2x - 2x + 1; w(x) - e*, [0, 0) Using integration by parts we find the following.
