How can you know which equation is true? 1/2 + 3/8 = 4/10 = 2/5
———————————————

A. Because 1+3=4 and 2+8=10, this equation must be true.

B. Because 2/5 < 1/2, this equation can not be true

C. This equation must be true, because when you add fractions the sum is always less than 1/2.

D. Because 3/8 < 1/2, this equation must be true.

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.
