I need help! Fin the inverse of the function, How do I work the below problem. I need an example do to all the examples I have all have an (fx, g or y) I am working 6 problems like this.

Question

{(1, 0), (2, 1), (-1, 0), (-2, 0)}

Answer 1

There will not be an inverse for this function. Not all functions have inverses.

Notice f(x) is zero when x=anythign other than 2. So, the inverse (zero) cannot map back to a specific x.

There has to be a one to one correspondence both ways x->y and y->x for inverses to exist.

Now if it had been something like this,
(1,0); (3,-3); (34,17); (0,3) the inverse would have been
(0,1);-3,3; 17,34; 3,0
