The asymptote for the graph of this logarithmic function is at x = 1
<h3>Further explanation
</h3>
An asymptote of a curve is a line such that the distance between the curve and the line approaches zero as one or both of the x or y coordinates tends to infinity. Whereas the logarithm is the inverse function to exponentiation and any exponential function can be expressed in logarithmic form.
First we solve 
Raise both sides of the equation by the base of the logarithm:

Because any non-zero number raised to 0 equals 1, the right side simplifies to 1
By using the property of logarithms that
where the left side simplifies to x-1
The equation is simply: x - 1 = 1
So x = 2.
The domain of a logarithmic function is the set of all positive real numbers. For example f(x) = log x also has an asymptote at x =0. But, since our function is log (x-1), we will move the asymptote to the right by 1 unit. Thus, x = 1. Which explains that the graph will never touch at x=1 which will be the vertical asymptote.
