$(2, 11)$

Work Step by Step

Notice that in $f(x)$ the $x$ is inside the parenthesis. This might help you remember that whatever is inside the parenthesis will be the $x-value$. $f(2)$ means that $2$ is the $x$-value. $f(x)$ can be substituted for $y$. This means that if $f(x)=11$, then $y=11$. Therefore the point is $(2, 11)$.
