So its a straight line up and then straight line horizontal. Then a line down. Finally a line that goes up.
Range is the second number in an ordered pair. Domain is the first. The correct answers are A, B, & D.
The correct option is first option: x=t(y-4f)
Further explanation:
Given equation is:

In order to solve the equation for x, we have to isolate x on one side of the equation
Using Subtraction property of equality
Subtracting 4f from both sides

Multiplication property of equality
Multiplying both sides by t

Hence, the correct option is first option: x=t(y-4f)

This is a great question, but it's also a very broad one. Please find and post one or two actual rational expressions, so we can get started on specifics of how to find vertical and horiz. asymptotes.
In the case of vert. asy.: Set the denom. = to 0 and solve for x. Any real x values that result indicate the location(s) of vertical asymptotes.
