what is the sum of 13 and 5? follow the steps to use 10 as an anchor to find the sum.
step 1: 10 + 5 = 15
step 2: since 13 is 3 more than 10, 3 more needs to be added to 15.
step 3: therefore, 13 + 5 =
8
12
18

step-by-step explanation:

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.
