Final answer:
The function f(x) = x² - 5x + 25 is a quadratic with no vertical asymptotes because it does not have a denominator that can be zero.
Step-by-step explanation:
To find the vertical asymptotes of the function f(x) = x² - 5x + 25, we need to consider where the function is undefined or approaches infinity. This particular function is a quadratic equation, which means its graph is a parabola. Vertical asymptotes are typically found in rational functions where the denominator can be zero, but in this case, since the function is a quadratic with no denominator, there are no vertical asymptotes.
