Fluency Practice

A table shows $g(1)=4$ , $g(2)=7$ , $g(3)=4$ , $g(4)=10$ . Does $g^{-1}$ exist as a function?

Yes, because every input has exactly one output.

No, because the output 4 appears for both inputs 1 and 3.

Yes, because we can still list the pairs in reverse order.

No, because the outputs don't include every integer.
