QuestionSuppose that the polynomial function $f$ is defined as follows. $$f(x)=6 x(x+5)(x-9)^{2}(x+7)^{3}$$
List each zero of $f$ according to its multiplicity in the categories below.
If there is more than one answer for a multiplicity, separate them with commas. If there is no answer, click on "None."
Zero(s) of multiplicity one: $\square$ $\square$ $\square$ , $\square$, None
Zero(s) of multiplicity two:
Zero(s) of multiplicity three: $\square$
