Okay so im really not in the mood sorry not worth that much points and hopefully you slept well and stuff like that but anyways : )

8 x 4 x 6 x 9 x 3 x 10 + 25 + 68 = ?

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.
