Task statements for students to write on. Unit: Alg2.2 Polynomials and Rational Functions (Algebra 2). Alg2.2 Polynomials and Rational Functions In this unit, students expand their understanding of polynomials from linear and quadratic to those of higher degree. They are introduced to situations polynomials can model. They study graphs and equations of the same function and make connections between factors and zeros. Students learn to divide polynomials and to sketch graphs of polynomials given in factored form. Building on this work, students investigate rational functions. They learn to interpret the meaning of asymptotes in context and strategies for solving rational equations. The unit conc
