Catalog Course Description
This is a continuation of Algebra IA. This is an integrated course that combines the content of algebra with logical reasoning, statistics, probability, problem-solving, real-life situations, spatial visualization, and introductory topics in geometry. The course format will include activity-based investigations with hands-on activities, concepts, and applications compliant with the adopted California State Mathematics Standards to meet the minimum course requirements for high school graduation. 60 lecture hours.
Course Objectives
- Identify and use the arithmetic properties of subsets of integers and rational, irrational, and real numbers, including closure properties for the four basic arithmetic operations where applicable.
- Understand and use operations such as taking the opposite, finding the reciprocal, taking a root, and raising to a fractional power. Understand and use the rules of exponents.
- Solve equations and inequalities involving absolute values.
- Simplify expressions before solving linear equations and inequalities in one variable.
- Solve multistep problems, including word problems, involving linear equations and linear inequalities in one variable, and provide justification for each step.
- Graph a linear equation.
- Verify that a point lies on a line, given an equation of the line. Derive linear equations by using the point-slope formula.
- Understand the concepts of parallel and perpendicular lines and how those slopes are related. Find the equation of a line perpendicular to a given line that passes through a given point.
- Solve a system of two linear equations in two variables algebraically and interpret the answer graphically. Solve a system of two linear inequalities in two variables and sketch the solution sets.
- Add, subtract, multiply, and divide monomials and polynomials. Solve multistep problems, including word problems, by using these techniques.
- Apply basic factoring techniques to second- and simple third-degree polynomials.
- Simplify fractions with polynomials in the numerator and denominator by factoring both and reducing them to the lowest terms.
- Add, subtract, multiply, and divide rational expressions and functions. Solve both computationally and conceptually challenging problems by using these techniques.
- Solve a quadratic equation by factoring or completing the square.
- Apply algebraic techniques to solve rate, work, and percent mixture problems.
- Understand the concepts of a relation and a function, determine whether a given relation defines a function, and give pertinent information about given relations and functions.
- Determine the domain of independent variables and the range of dependent\\nvariables defined by a graph, a set of ordered pairs, or a symbolic\\nexpression.
- Determine whether a relation defined by a graph, a set of ordered\\npairs, or a symbolic expression is a function and justify the conclusion.
- Become familiar with the quadratic formula and its proof by completing\\nthe square.
- Use the quadratic formula to find the roots of a second-degree\\npolynomial and to solve quadratic equations.
- Graph quadratic functions. Use the quadratic formula or factoring\\ntechniques or both to determine whether the graph of a quadratic function will intersect the x-axis in zero, one, or two points.
- Apply quadratic equations to physical problems.
- Understand and use simple aspects of a logical argument (inductive and deductive reasoning, hypothesis and conclusion in logical deduction, counterexamples).
- Use properties of the number system to judge the validity of results,\\njustify each step of a procedure, and prove or disprove statements.
