An unopened cereal box contains 1528 cubic foot of cereal. if the box is full, and the length and height of the box are 57 and 112 feet, respectively, what is the width of the box?

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

as before, graphs and tables allow us to estimate at best.

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.
