if x = 12 in, y = 16 in, and z = 20 in, what is the surface area of the geometric shape formed by this net?

13

step-by-step explanation:

distance formula is d=√(x2-x1)^2   +   (y2-y1)^2

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

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.
