So for this problem, we are given the function y equals to the x, and that function, if i were to graph, goes through 0 .1.
00:10
If i were to plug in 1 for x, i would get 2.
00:15
2 for x, 2 squared would give me 4, and negative 1 would give me a 1⁄2.
00:23
So it would look like this.
00:29
Now i have to find the inverse of this exponential by changing f of x into an x, and x into a y.
00:38
And then i want to get this y by itself.
00:40
And to do that, i'm going to change this into a logarithmic function...
