Which description compares the vertical asymptote(s) of Function A and Function B correctly?

 

Function A: f(x)=1/x−3

Function B:

 

 

Function A has two vertical asymptotes.
Function B has one vertical asymptote.

 

Both functions have a vertical asymptote at x = 4.

 

Function A has a vertical asymptote at  x=−3 .

Function B has a vertical asymptote at x = 4.

 

Function A has a vertical asymptote at x = 3.
Function B has a vertical asymptote at x = 4.

Function A

f(x)  =  1 / ( x - 3)

The  vertical asymptote is  the value of x that makes x - 3 = 0 ⇒   x = 3

 

The vertical asymptote of B   is  x = 4

 

So....

 

Function A has a vertical asymptote at x = 3.
Function B has a vertical asymptote at x = 4.
