Let f be defined and continuous on [a,b]. Then for each x [a,b] there exists a polynomal p(x) such that p(x)-f(x)| 0. This theorem allows us to: Select one: O a. approximate the function f by a Lagrange Interpolating polynomial p O b. subtract any function f from a polynomial p O c. find limits of functions O d. apply the fundamental theorem of algebra for any polynomial p
