I can’t remember the last time the intersecting chords theorem appeared in a syllabus I was teaching, but it is still very much around. So, of course, it deserves its own Transum exercise.

There are a number of ways of expressing the domain of a function and hopefully they're all covered here in this new multiple-choice exercise. Choose the level consistent with your syllabus.
