There are several mistakes in the code, e.g., not ending the
center environment, using nonsense sequences of commands and environment etc.
If I delete all the nonsense code and make a
minimal working example from the code snippet:
Code: Select all
\documentclass{article}
\begin{document}
What would happen as $x$ approaches $3$? We can figure this out by applying a limit.
\[ \lim_{x\to 3} g(x) \]
\end{document}
I do not see any problem with the code. So maybe you should either clean up your code or show us a real
minimal working example. And please mark code correctly as code using the
Code button instead of the
LaTeX button. The
LaTeX button is for inline code only, but not for
block code.
