\hypersetup{
colorlinks = true, %Colours links instead of ugly boxes
urlcolor = blue, %Colour for external hyperlinks
linkcolor = blue, %Colour of internal links
citecolor = blue %Colour of citations
}
\begin{document}
\begin{equation*}
f(x,y) = \left\{
\begin{array}{lll}
\frac{y}{x} \quad \text{if} \quad x < a ; \\
[x,y] \quad \text{if} \quad x=a; \\
\frac{x}{3y}\quad \text{ if } \quad x
> a.
\end{array}
\right.
