Core sequence
Algebra and Function Readiness
Move in order when the material is new, or enter at the exact skill you need.
- 01Readiness diagnostic and routingUse diagnostic evidence to identify which prerequisite strands are secure and which require targeted repair.
- 02Equation and inequality repairClassify and solve common equation and inequality families while distinguishing reversible steps from candidate-generating steps.
- 03Factoring and polynomial structure repairRecognize and apply the principal factoring structures needed for polynomial-function analysis.
- 04Rational expressions and restrictions repairSimplify and solve rational expressions while preserving every restriction from the original form.
- 05Radicals and rational exponents repairMove among radical and rational-exponent forms, simplify exact values, and reject extraneous candidates.
- 06Exponential and logarithmic algebra repairApply exponent and logarithm laws, convert between inverse forms, and solve basic equations with valid domains.
- 07Function notation and graph reading repairEvaluate functions, solve output conditions, and read domain, range, intercepts, extrema, and intervals from graphs.
- 08Mixed readiness synthesisSelect methods across prerequisite strands, justify restrictions, and communicate exact and approximate results.
