The first function

Step-by-step explanation:

A function's y never repeats. The only inverse that follows that rule is the first function.

Which function has an inverse that is also a function?{ (-4, 3), (-2, 7), (-1,0), (4, - 3), (11, - 7) }{ (-4, 6), (-2, 2), (-1, 6), (4,2), (11, 2) }{ (-4,5), (-2, 9), (-1, 8), (4, 8), (11, 4) }{ (4,4), (-2,-1), (-1,0), (4, 1), (11, 1) }
