f(x)=(x-3)/(x+2)

The domain of a fuction has conditions when we have an on the denominator because the value of the denominator would be 0 and the deivsion between 0 isnt posible

Then we need to check the values of x than makes 0 the denominator and this values are out of the Domain


\begin{gathered} x+2=0 \\ x=-2 \end{gathered}

So, the Domain is all real values of X such that x is different to -2 , then right option is A
