    after that silliness, the domain of any polynomial, unless otherwise stated, is "all real numbers"

    So it would be the second option? @satellite73

    As satellite said, the domain will be all real numbers unless noted otherwise. But for this question we have to take into consideration the denominator. Can you factor the denominator?

    (x−3)(x+3) right? @TheSmartOne Thus it would be the second option?

    correct, now what would happen if the denominator of any fraction is equal to 0? \(\sf\Large\frac{1}{0}=?\)

    It couldnt be divided so the numerator would be the same?

    So the domain has to be all real numbers except for the values which make the denominator equal to 0

    set each equal to 0 to find out (x−3)=0 (x+3)=0
