Choose and use conjugates to evaluate radical limits, preserving signs, factors and real-domain restrictions. Requires finite-limit laws and algebra with radicals. Practice includes one-sided endpoint approaches and a measurement-change interpretation.

Use common factors to resolve removable algebraic singularities while retaining the original exclusions. Requires finite-limit laws and elementary factoring. Distinguish nearby equality, the original function value and a separately defined filled-in value.
Oct 27, 2026
Apply finite-limit laws and decide when direct substitution is justified. Requires one-sided limit interpretation and basic algebra. Practice includes nonzero-denominator and real-domain checks, indeterminate forms, and method selection; no derivative shortcut is used.

Review point values, one-sided limits, unbounded behavior and end behavior across exact graph descriptions and numerical evidence. Requires the six Understanding limits lessons or equivalent competence. Use the results to identify a specific skill to revisit; this checkpoint introduces no new method.

Interpret long-run behavior at each infinite-input end and identify horizontal asymptotes. Prerequisites: function notation, limit meaning and exponential structure. Distinguish tail behavior, crossings and finite-time attainment.
Oct 27, 2026
Interpret signed unbounded behavior near finite inputs and distinguish vertical asymptotes from removable holes. Prerequisites: one-sided limits and elementary factoring with domain exclusions. Check sides separately and interpret singular models.
Oct 27, 2026
Recognize jumps, unbounded behavior and persistent oscillation, and distinguish them from shrinking oscillations. Prerequisites: interpreting sampled limits and radian sine values. Explain which behavior prevents a finite limit.
Oct 27, 2026
Estimate limits from two-sided tables and distinguish numerical or graphical evidence from an exact guarantee. Prerequisite: one-sided and two-sided limit meaning. Practice cautious reporting, precision and useful resampling.
Oct 27, 2026
Interpret left-hand and right-hand approach and decide when a finite two-sided limit exists. Prerequisite: point values versus nearby limits. Use exact graphs, piecewise formulas, endpoint domains and threshold models.
Oct 27, 2026
Learn to separate a function value from its finite nearby limit. Prerequisite: function notation and graph endpoints. Interpret exact graph specifications, deleted neighborhoods and local model behavior before using calculation rules.
Oct 27, 2026
Practice exponential structure, real logarithm domains and multiplicative models. Prerequisite: function notation and algebra. Translate representations, preserve restrictions and choose logarithms to isolate an exponent.
Oct 27, 2026
Practice radian measure, exact trigonometric structure and principal inverse branches. Prerequisite: function notation and domains. Use unit-circle, graph and model reasoning to prepare for later calculus without assuming derivative or limit formulas.
