Continuity and discontinuities

Practice continuity and discontinuities through coordinate graphs, piecewise formulas and domain restrictions. Check existence, limiting behavior and point-value agreement, then solve matching problems and interpret continuity at endpoints.

Build from interpretation to calculation, transfer and error diagnosis. Work out each answer before viewing the choices; single-select and select-all questions include worked explanations for checking assumptions and reasoning.
