What is 2/3x + 15 = 17

Depends, x=1/3 if x is in denominator, x=3 if it's after the fraction.

Step-by-step explanation: You subtract 15 from both sides, you end up with 2/3x=2. Now if the x is in the denominator, your answer will be 1/3. But if the x is outside the fraction (or ahead of it) the answer will be 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.
