00:01 I actually understand your confusion on this one because on the first one, this has an inverse.

00:07 The inverse of this, so here's the graph of the function, the inverse will end up being this function where you have x squared, where x has to be greater than or equal to zero.

00:19 For your f of x equals 2x to the 3rd minus 4, that function looks like this, and that function will have an 8...
