The population of city A is 0.6 million less than the population of city B, and the population of city C is three times that of city B, decreased by 2.7 million. If the sum of the populations of city A, city B and city C is 78.2 million, find the population of each city.

figure c

answer: your correct answer is b. d.

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.
