Which statement is correct using "is not equal to'' (≠)? A) 3 5 of a gallon 60% of a gallon. B) 4 5 of a gallon 90% of a gallon. C) 5 10 of a gallon 50% of a gallon. D) 9 20 of a gallon 45% of a gallon.

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.

if you are factoring then 4(x+3)

if you are simplifying 4x+12
