Key takeaway: Algebra 2 vocabulary covers 39 eleventh-grade terms, including complex number, synthetic division, asymptote, logarithm, geometric series, unit circle and z-score.
Algebra 2 widens the family of functions: polynomial, rational, logarithmic and trigonometric graphs all appear in the same year. This Algebra 2 vocabulary page for Grade 11 collects the words needed to describe them, solve their equations and read their graphs.
It also includes the statistics of the course, such as the normal distribution and margin of error. Each definition comes with the notation, a figure and a worked problem that uses unusual numbers, not textbook classics.
39 terms on this page, each with a definition, a figure and a worked example.
