Unit 2: Polynomial Functions
Students extend their work with linear and quadratic functions to polynomials of higher degree, moving flexibly between standard and factored forms, sketching graphs from key features (zeros, multiplicity, end behavior), and dividing polynomials to apply the Remainder Theorem.
