Algebra II at a Glance Unit 1: Complex Numbers • Define the imaginary unit • Perform operations involving complex numbers, rationalizing numerators and denominators and determining the modulus of a complex number, plot complex numbers on a complex plane. • Solve quadratic equations with complex solutions - connect the discriminant with the number and type of zeros and number of x-intercepts. • Transform any quadratic equation in x from standard, vertex, or factored form to any of the other forms. • Graphing quadratic equations in all forms: standard, vertex and factored (review) • Solve quadratic inequalities in two variables Unit 2: Functions • Use interval notation. • Define, use and interpret function notation; evaluate functions. • Define and use vocabulary of relations and functions (relation, domain, range, input, output, function, independent/dependent variable, zero). • Interpret multiple representations (algebraic, graphical, table of values, list of ordered pairs, mapping diagram, and verbal description) of functions; identify, use, and create different representations of the same function. • Perform operations on functions including composition using multiple representations. • Perform transformations of graphs of functions (to include linear, quadratic, sine and cosine, piecewise-defined including absolute value, and the step function) with multiple representations. • Identify and apply characteristics and behaviors of functions including domain, range, intercepts, zeros, intervals of increasing/decreasing/constant behavior, relative and absolute extrema, end behavior (Function presented graphically.) Unit 3: Polynomials • Simplify polynomial expressions - using addition, subtraction, multiplication and long division of polynomials. • Define a polynomial function; identify the degree, leading coefficient and constant term of a polynomial function. • Known and apply the Remainder Theorem. • Graph polynomial functions presented in factored form or that are factorable using the leading coefficient test, the multiplicity and type of zeros, the Fundamental Theorem of Algebra and the maximum possible number of extrema. • Write an algebraic representation for a polynomial function when given sufficient information (including a graph). • Solve polynomial equations.
