So here we would like to use a graph and a table of this function.
00:04
Desmos can do both of those things.
00:05
X is equal to 1 minus 2 over x to the power of x.
00:12
To estimate the value of the limit as x goes to infinity of f of x, so you look at this, expand this out a little bit, so we get some more space.
00:22
X goes to infinity, and it looks like it's evening out at about, what is this, a bit more than, what is this, 0 .0.
00:32
This is 0 .01, so it's going up to about 0 .12, maybe? so it looks like the limit is approximately equal to 0 .12.
00:51
I don't know.
00:54
We're going to need to estimate it, and that seems right.
00:56
It's certainly not going up to 1 .3, and it's not 1 .1 either, so 1 .2 seems accurate to two decimal places.
01:05
I'm going to use a table to get to the four decimal places.
01:08
We can do that here by not duplicating it but making a table.
01:13
Now if you have x, it's going to be 1, 10, 100, 1 ,000, 10 ,000, 100 ,000.
01:26
It looks like we were wrong.
01:27
It is actually going to get up to 0 .13...
