Morphology
single-valued + function
The term is compositionally built from 'single' (one) + 'valued' (having a value) and 'function' (a mapping), so the idea that each input maps to one output is directly derivable from the constituents. Although it's a technical mathematical phrase, the compounding follows regular English patterns, making it understandable to a B1 learner who knows the component words.
Etymology
Single-valued function is like a button on a vending machine: press the same button (the input) and the machine gives one specific snack (the value) every time. So a single-valued function means 'one output for each input', never more than one.
