which of the following rational functions is graphed below A.f(x)=1/x-4 B. F(x)=1/4x

Considering it's vertical asymptote, the rational function graphed below is given by:
A. [tex]F(x) = \frac{1}{x - 4}[/tex].
The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.
In this graph, there is a vertical asymptote at x = 4, that is, x - 4 is a term of the denominator, hence the function is given by:
A. [tex]F(x) = \frac{1}{x - 4}[/tex].
