How do you simplify and find the excluded values of 2/(y-9)?

$\text{excluded value } = 9$

Explanation:

$\frac{2}{y - 9} \text{ is in simplest form}$

The denominator cannot equal zero as this would make the function $\textcolor{b l u e}{\text{undefined}}$
Equating the denominator to zero and solving gives the value that y cannot be.

$\text{solve " y-9=0rArry=9larrcolor(red)" excluded value}$
