There are two possible situations for this kind of thing:
>there is no single place where they're closest
>there is a place where they're closest
If there is a place where they're closest (and there is in this case, just graph it), the usual trick is that the line connecting the points where they're closest is orthogonal to both curves. One of those is a line, which closes things off nicely.
