The rational function shown in the graph above has a hole at $\displaystyle {x}=$ and a vertical asymptote at $\displaystyle {x}=$ .

If this function has the form $\displaystyle {Q}{\left({x}\right)}={\frac{{{x}-{b}}}{{{\left({x}-{a}\right)}{\left({x}-{b}\right)}}}}$

then $\displaystyle {a}=$

and $\displaystyle {b}=$.
