📄 Overview & Study Guide
Build practical confidence in functions, graphs & summation notation through 20 original single-select and multiselect questions. Prerequisites: Elementary algebra, powers and logarithms.
Read coordinates and interpret slopes with units. Evaluate functions and identify valid domains. Invert or compose functions with appropriate restrictions. Expand and transform finite indexed sums. Evaluate finite products and factorials. Reason about piecewise boundaries and limits of tabular inference. Questions progress from basic recognition to application, interpretation and diagnostic challenges. Worked feedback explains the reasoning and the alternatives; no programming or calculus is needed.
