Aball is thrown from an initial height of
4 feet with an initial upward velocity of
29 ft/s. the ball's height h
(in feet) after t
seconds is given by the following.

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.
