Course Title: Algebra 2 with Trig Unit: Polynomials (1st Semester) Glenbard District 87 Unit Title: Polynomials Stage 1 – Desired Results Established Goal(s):What relevant goals (e.g. Content standards, course or program objectives, learning outcomes, etc.) will this address? F-‐IF.4. For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; F-‐IF.7. Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases; Graph polynomial functions, identifying zeros when suitable factorizations are available, and showing end behavior. • A-‐APR.2. Know and apply the Remainder Theorem: For a polynomial p(x) and a number a, the remainder on division by x – a is p(a), so p(a) = 0 if and only if (x – a) is a factor of p(x). • A-‐APR.3. Identify zeros of polynomials when suitable factorizations are available, and use the zeros to construct a rough graph of the function defined by the polynomial. N-‐CN.8. (+) Extend polynomial identities to the complex numbers. For example, rewrite x2 + 4 as (x + 2i)(x – 2i). N-‐CN.9.
