Algebra 2 Vocabulary
In short: Algebra 2 vocabulary: 39 terms on polynomial, rational, exponential, and logarithmic functions, complex numbers, and sequences, each defined in plain words with a worked example to help decode any problem.
The algebra 2 vocabulary list below covers the words that appear when functions get more advanced: zero, multiplicity, asymptote, inverse, logarithm, imaginary unit, conjugate, arithmetic series, conic section. Each entry offers a short definition and an example that shows the term working inside a real equation.
It is handy while you do homework, especially when a prompt asks you to “describe the end behavior” or “find the extraneous solution.” Print the sheets before a test and mark the words you hesitate over. Then rewrite those definitions in your own words; if you can teach the term to a classmate, you own it.
39 words on this page, each with a definition, a figure, a solved example and two quick questions.
