Algebra 2


Algebra 2

Course Description:

This course extends the skills and concepts introduced in Algebra 1 and covers the
following topics: absolute value inequalities; linear, quadratic and absolute value
functions (their graphs and defining features); properties of exponents including
negative, zero and fractional values; systems of linear and quadratic equations and
inequalities; quadratics equations with complex number solutions; exponential and
logarithmic functions (properties, graphs, solving equations and applications);
polynomial functions (graphing, finding zeros and important theorems); square root and
cube root functions; rational functions (graphing, finding zeros, and asymptotes); and
conic sections. Also, since problem solving is an integral part of this course, students
spend a considerable amount of time translating problems presented in written form to
equivalent statements in mathematics. Then, the students find solutions to the
problems and express the results in written form. Algebra 2 is a prerequisite for all
advanced math courses.

Course Objectives:

  • Students will be able to analyze and evaluate the characteristics of step, piece-wise,
    exponential, and quadratic functions, as well as inverses of functions
  • Students will interpret and apply the characteristics of functions with regard to a given
    context and analyze and evaluate rates of change, both constant and variable, within
    the basic function families.
  • Students will be able to analyze and evaluate geometric and arithmetic sequences as
  • Students will analyze and solve quadratic equations using a variety of techniques and
    represent, simplify, and operate with complex numbers.
  • Students will be able to analyze and solve problems involving probabilities,
    permutations, and combinations, as well as analyze and evaluate sample data,
    making inferences about population means and standard deviations and using these
    inferences to compare data sets.
  • Students will understand and apply algebraic models to quantify the association
    between two quantitative variables.
