vertical asymptote: $x=1$

Vertical asymptotes occur where the denominator is zero. Thus, we set the denominator to zero and solve for the $x$ values to find the vertical asymptotes: $x-1=0\\x=1$ Hence, the vertical asymptote is $x=1$. Here, the degree of the numerator is larger than that of the denominator. Thus, there is no horizontal asymptote.
