Does this graph represent a function? why or why not? 1-10 -5 4 267 2 4 6 8 10 o a. no, because it is not a straight line. o b. no, because it fails the vertical line test. o c. yes, because it passes the horizontal line test. o d. yes, because it passes the vertical line test.

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.
