Suppose that you are given the derivative of a function

$f^{\text{'}}(x)=(x5)(9-x)(17-x)$

Then the first relative extremum $($from the left$)$ for $f(x)$ occurs at $x=$

The function $f(x)$ has a relative $$ at this point.

The second relative extremum $($from the left$)$ for $f(x)$ occurs at $x=9$

The function $f(x)$ has a relative $$ at this point.

The third relative extremum $($from the left$)$ for $f(x)$ occurs at $x=$

The function $f(x)$ has a relative $$ at this point.

Find the second derivative $f^{\text{'}\text{'}}(x).$

The first inflection point $($from the left$)$ for $f(x)$ occurs at $x=$
