A function value refers to the output of a function for a given input. If "4" is considered a function value of $f$, it means that for some input $x$, $f(x) = 4$. Without specific information about the function $f$, we cannot definitively say it's not possible; hence, we must consider it possible that "4" could be a function value of $f$.
