Final answer:
If a function does not have a denominator, it means that the function is defined for all values of the input variable x and does not have a vertical asymptote.
Step-by-step explanation:
To find the vertical asymptote of a function without a denominator, we need to look for any values of the input variable that would make the function undefined. In this case, if the function does not have a denominator, it means that the function is defined for all values of the input variable x. Therefore, the function does not have a vertical asymptote.
