Answer:
x - 5
Step-by-step explanation:
For maximum clarity please write this function as
2
f(x) = ------------
x - 5
The vertical asymptote is at x = k, where k is the x value that makes the denominator of this fraction be zero.
In this particular problem, the denominator is zero at x = 5, and so the equation of the vertical asymptote here is x = 5.
