Answer:
[tex]x=0[/tex] for [tex]f(x)=\frac{P(x)}{Q(x)}[/tex], with [tex]Q(x) \neq 0[/tex].
Step-by-step explanation:
To obtain x-intercepts, we need to give certain value, specifically [tex]x=0[/tex].
However, in case of a rational function, we must make sure that [tex]x=0[/tex] doesn't makes the denominator null, beacuse in that case the function is undefined.
Therefore, for x-intercepts we must say
[tex]x=0[/tex] for [tex]f(x)=\frac{P(x)}{Q(x)}[/tex], with [tex]Q(x) \neq 0[/tex].
