Which rule describes the relationship between the x- and y- coordinates on the following graph? Choose 1 (Choice A)
A
y
=
2
x
y=2xy, equals, 2, x

(Choice B)
B
y
=
x
+
2
y=x+2

A

Step-by-step explanation:

given the points

(0, 0 ) , (2, 4 ) , (4, 8 )

note that the y- coordinate is twice the value of the x- coordinate , so

y = 2x

answer: what do you mean

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.
