So it looks like there's a little bit of assistance that is needed here.
00:06
For y equals 1 over x, that is actually what we would call a ratio, one number over another one, which actually makes sense why we call it a rational function then.
00:21
If you're kind of curious why you might call it an inverse function, is because you could have rewriting it as y equals x to the negative first.
00:29
So it is okay.
00:31
But anyway, this first one would be option e.
00:34
So that one was good.
00:36
Moving on to the next one, y equals the square root of x.
00:42
And i just said it.
00:43
It's the square root.
00:47
So as i look through those options, the square root is option b on that one.
00:53
So e, b so far.
00:55
The next one is y equals 2 to the x.
00:58
And what i tell people is when the exponent is the index, independent variable because sometimes it's t, sometimes it's a different letter.
01:14
That's what makes it exponential...
