Please solve and explain, thanks!! :))

B. 8x + 12

Step-by-step explanation:

First you'd start with the parentheses because of PEDMAS. But because you can't do anything in there, you go to multiplying 4 by each item inside the parentheses. 4x2x gives 8x. 4x3 gives 12. Leaving you with 8x+12. Hope that helps! :)

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.
