Graph Rational Functions and Identify Asymptotes Practice Test

Identify the vertical asymptote(s) and any holes of the rational function $$f(x) = \frac{(x-4)(x+1)}{(x-4)(x-2)}.$$

For $$f(x)=\frac{(x+2)(x-1)}{x^2-4},$$ find the zeros, vertical asymptote(s), and any hole. (Use factorization to decide whether a common factor creates a hole.)
