You can put this solution on YOUR website! The one-to-one function g is defined by
g={(-7,-9),(6,3),(7,6),(8,-1)}
----
"g" is a machine. When you give it 7,
it gives you 6.
------------------------------
Find the following...
g^-1(6)= ?
----
"g^-1" is the same machine, but it is running backward.
When you give it 6, it gives you 7.
----
Ans: g^-1(6) = 7
