which of the following rational functions is graphed below?

The rational function represented in the given graph is; f(x) = 1/(x - 4)
From the given graph , the vertical asymptote is at x = 4
Let's find out the vertical asymptote of each function
To find out vertical asymptote we set the denominator = 0
A) x + 4 = 0
x = -4
This is not correct
B) 4x = 0
x = 0
Not correct
C) Denominator does not have a variable and so is also incorrect
D) x - 4 = 0
x = 4
Thus, this is correct
