Algebra, domains and valid reasoning

Assess cumulative precalculus algebra through mixed equations, inequalities, domains and valid reasoning. This set asks you to select methods, combine restrictions and decide whether a transformation preserves the original problem.

Twelve fresh single-select and multiselect questions include parameter cases, reciprocal domains, distance constraints, radical equations, simultaneous inequalities and unknown-function reasoning. No method labels are supplied in the questions. Detailed post-attempt explanations justify accepted and rejected possibilities. Use scratch work and treat domain errors as specific review targets rather than relying only on the total score.
