The inverse of a function is often described in the following way.
00:03
We create the inverse denoted by f to the negative 1 of a function f by reversing the rules of the input in the output f, for example.
00:10
If f of 3 is 7, then f inverse of 7 is 3.

So with numerical exchange, if we have g of x and we know g of x and f of x are inverses, then if we know that, for instance, 6 negative 5, negative 5, 6.

So if the input is 4, that was the output of 4 here and that must be going with negative 2.
00:43
And the input of this function, f, would be the output of g if there are functions or inverse functions, and so that would be 7.
00:51
7 -8 goes to 8, 7 with its inverse.
00:57
The graph of a function is given sketch in the same set of axes, the graph of possible inverse of f, is your sketch of an inverse a function.

Can we find the inverse for this function? so what i would do is pick points that are somewhat easy to read, maybe even still a critical point here, but if we invert zero zero we get zero, we just switch the order pairs around.

If one six is on the function, then six one is on the inverse...
