Liz attempted to factor 36. Since 36 = 3*12 and not 3+12, this is not the way to go. In stead of factoring 36, she should have split it into a friendly sum, like 36=30+6.

Then Step 1 should have been 27(6+30).

<span> x2 – 12x + 36 = 4
(x - 6)^2 = 2^2

x - 6 = 2
x = 8

-(x - 6) = 2
-x + 6 = 2
-x = -4
x = 4

How do you find the equations of the vertical and horizontal asymptotes for a graph when you only have the graph and no function

-BARSIC- [3]

Answer:

See below for answer and explanations (as well as an attached graph)

Step-by-step explanation:

Pay attention to the behavior of the asymptotes. If the asymptotes are approaching a certain x-value or y-value, then that value is undefined for the function.

Take for example $y=\frac{1}{x}$ :

As x approaches ∞ and -∞, then y approaches 0, which is our horizontal asymptote

As y approaches ∞ and -∞, then x approaches 0, which is our vertical asymptote

See the graph for a visual.
