In this problem, we are given the one -to -one function f of x, which is equal to the square root of x, where we have the condition, x must be greater than are equal to zero.
00:09
So i just want to indicate what this would look like.
00:11
Remember that the square root function of x would look something like this, where the x values are, in fact, all greater than zero.
00:20
So our task here is to find the inverse.
00:24
So in order to do that, we're first going to take a look at switching the x and y values.
00:29
So you might be wondering where there's a y in this equation, and that is the same as f of x.
00:38
So i'm going to take the y and the x and swap their spots.
00:41
So now we have x equals square root of y...
