To find the domain of the function \( f(x) = \frac{x+1}{x+2} \), we need to determine the values of
for which the function is defined. The function is a rational function, and it is defined for all real numbers except where the denominator is zero.The denominator of the function is
. We set the denominator equal to zero to find the values of
that are not in the domain:
Solving for
:
Therefore, the function \( f(x) = \frac{x+1}{x+2} \) is undefined at
.The domain of
is all real numbers except
. In interval notation, the domain is:
So, the domain of
is:
