Yes — "Yes, each student's unique identification number is paired with just one grade level."

Reason: A function requires each input (student number) to have exactly one output. Each unique student number corresponds to one student, and each student has a single grade level, so each student number maps to exactly one grade. (It's fine that many student numbers may map to the same grade.)
