Suppose that the functions r and s are defined for all real numbers x as follows. r(x) = 4x+3
s (x)=6x
Write the expressions for (r+s)(x) and (rºs)(x) and evaluate (r-s)(3).

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.
