A candle is 6 inches tall and burns at a rate of 1/2 inch per hour. If the candle is now 3.5 inches, how many hours has it been burning?

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
