(1 point) an open box is to be made from a flat piece of material 12 inches long and 5 inches wide by cutting equal squares of length from the corners and folding up the sides. write the volume of the box as a function of . leave it as a product of factors, do not multiply out the factors.

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.
