Okay, here i want to find a domain of this function.
00:05
When you find domains of functions, there are two things that to deal with.
00:09
One, you can't have square roots of negative numbers, so that's not allowed.
00:15
And you can't have 1 over 0.
00:18
You can't divide by 0.
00:20
Those two things you deal with in domains.
00:24
So let's deal with this one first.
00:27
What that means is this bottom part cannot be 0.
00:32
4 minus the square root of 3x minus 2 can't be 0, which means 4 cannot be the square root of 3x minus 2.
00:47
If i square both sides, 16, 3x minus 2, 18 can't be 3x.
00:56
For the words, x cannot be 6.
00:59
So that's the first thing we know.
01:02
We can't have x as 6...
