Just be so kind and add some own effort, thoughts you had so far trying to solve it.

The wording "precalculus" and "calculus" isn't perfect. It's pretty easy: if it has a derivative it's calculus and if not it's precalculus. But we can move wrongly located threads, so don't put too much thought in it.
