[Tex/LaTex] Emphasize the exponential function in the text

emphasismath-mode

I want to typeset something like this:

[...] $y = \exp(x)$, where $\exp$ is the exponential function.

However, I don't like that $\exp$ is not at all emphasized in the text. What are good alternatives? Is leaving math mode a good idea?

[...] $y = \exp(x)$, where \textit{exp} is the exponential function.

Somehow, this does not seem very elegant.

Best Answer

I would not recommend changing the font style, I would rather add some redundant information, such as the definition of exp, or set it in quotes.

\documentclass{article}
\begin{document}
$y = \exp(x)$, where $\exp\colon x \mapsto \mathrm{e}^x$ is the
exponential function.

$y = \exp(x)$, where ``$\exp$'' is the exponential function.
\end{document}
