$\setminus {\lim}_{x \to 1} 4 = 4$

Note that the function $f \left(x\right) = 4$ is a straight line where the function is equal to 4 no matter what $x$ is so the limit is 4 no matter where it is.

The answer is correct. Although obvious, there is a limit law that you should use for your reasoning:

${\lim}_{x \to a} c = c$
