Edward is correct if the x values have factors located in the denominator. When this happens, you have vertical asymptotes.

Bella is correct when the x values have factors located in the numerator ONLY. When this happen, you have x-intercepts.

They are both correct when their factors are in both numerator and denominator. When this happens, you have a hole. This means the values are defined, but are also undefined.
