Question

A. f(x)=1/x+4 b.f(x)=1/x-4 c.f(x)=1/x+4 d.f(x)=1/x-4

Answer 1

Answer:

The correct answer is c. f(x) = 1/(x + 4)

Step-by-step explanation:

We can tell this because as the bottom of the equation (x + 4) approaches 0, the equation gets larger and larger.

Also, you can note that -4 is a asymptote, which can only be from the bottom of the equation being equal to 0. This is only true in option c.
