Syllabus Algebra 1B Course Overview Algebra is a branch of mathematics that uses symbols in place of numbers to describe and generalize relationships. You already have experience with expressions containing monomials and binomials. In Algebra 1B, you ll extend these ideas to factor and perform operations on polynomials which are expressions with more than two terms. Until now, many of the equations that you ve solved have been linear, or proportional. In Algebra 1B, you ll begin to solve quadratic equations. These are equations where the highest power on any variable is two. You ll look closer at the parabola, a conic section defined by a quadratic equation. Additionally, you ll build your graphing skills by analyzing and plotting different types of functions: absolute value, piecewise, exponential, and logarithmic. Finally, you ll learn more about statistics as you interpret the shapes of data distributions and delve into correlation and causation. Course Goals By the end of this course, you will be able to do the following: Add, subtract, multiply, divide, and factor polynomials. Solve quadratic equations by factoring or using the quadratic formula. Determine the orientation of a parabola and find its x- and y-intercepts and its vertex. Analyze exponential and logarithmic functions. Graph absolute value and piecewise functions. Calculate the composite and inverse of a function. Solve real-world problems involving linear, quadratic, and exponential functions. Interpret the statistical similarities and differences between two or more data sets. Distinguish between correlation and causation. Math Skills Algebra 1A is a prerequisite course for Algebra 1B. Before beginning this course, you should be able to do the following: Add, subtract, multiply, and divide monomials and binomials. Solve and graph linear equations and inequalities in one or more variables. Understand patterns, sequences, series and functions. Solve problems involving linear functions. Apply rules for exponents and radicals. Interpret the features of a line from an equation written in point-slope or y-intercept form. 1 2013 EDMENTUM, INC.
