Katie is studying the Euler equation $x^2y''+xy'-4y=0$. She knows that the solution for $x>0$ can be solved by making the substitution $u=\ln x$, but she is interested in the asymptotic behavior of solutions at infinity so this substitution is not very helpful.

For this purpose, she thinks the substitution $\xi=1/x$ is suitable.

By her method, the point at infinity is:


an ordinary point.


a regular singular point.


an irregular singular point.


None of the above.
