what is the domain of x+1 in interval notation

The expression \(x + 1\) is a linear function, and there are no restrictions on the value of \(x\). This means that \(x\) can take any real number.

Thus, the domain of \(x + 1\) is all real numbers, and in interval notation, the domain is:

\[
(-\infty, \infty)
\]
