The standard notation is $\lim_{x \to a} f(x) = L$. This symbolizes that as the independent variable $x$ approaches the value $a$, the dependent variable $f(x)$ approaches the limit value $L$.

Conditions: $a$ is the value $x$ approaches.; $L$ is the limiting value of $f(x)$.; $f$ is the function being analyzed.
