Answer
False
Work Step by Step
We know that $\lim\limits_{x \to a} k(x)=k(a)$, where $a$ as a constant, for continuous functions.
We know that a rational function may not be continuous at the limit $5$. For example, consider:
$\lim\limits_{x \to 5} f(x)=\lim\limits_{x \to 5} \dfrac{1}{x-5}= \ Undefined$
So, the statement is $\bf{False}$ .
