If a function has a vertical asymptote at a certain x-value, then the function is undefined at the value.
What is the vertical asymptote of a function?
"Vertical asymptotes of a function f(x) = m(x)/n(x) can be found by solving the equation n(x) = 0. Here n(x) is the denominator of the function."
Let, a function is defined as
f(x) = 1/x
Here, the denominator of the function f(x) is 'x'.
Therefore, f(0) = 1/0 = undefined.
f(x) is undefined at x = 0.
Again, to find out the vertical asymptote of the function f(x), we need to take x = 0.
Therefore, when a function has a vertical asymptote at a certain x-value, then the function is undefined at that particular value.
