Erickson · Answer 1

A function for which every element of the range of the function corresponds to exactly one element of the domain ... Note: y = f (x) is a function if it passes the vertical line test. It is a 1-1 function if it passes both the vertical line test and the horizontal line test.

A one-to-one function is a function in which the answers never repeat.
