Question

In a rational function, what must be true (or what must happen) for an equation to
have vertical asymptote(s)?​

Answer 1

Answer:

These vertical asymptotes occur when the denominator of the function, n(x), is zero ( not the numerator). ... Vertical asymptotes can be found by solving the equation n(x) = 0 where n(x) is the denominator of the function ( note: this only applies if the numerator t(x) is not zero for the same x value).
