This table shows a proportional relationship between x and y. Find the constant of proportionality (r). Using the value for r, enter an equation in the form of y = rx. Write the values of r in the form of a whole number or fraction.

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.
