Algebra 2, with Trig

Using synthetic division, Thus, Theorem: A polynomial function cannot have more real zeros than its degree. * That is, if a function f has degree n, the function f will have at most n real zeros. For example, has degree n = 4, has at most ( no more than) 4 real zeros. In this case, f has one real zero, x = -3. *Proof: Descartes’ Rule of Signs: ................
