There's a couple ways that you could explain this problem, but they do ask that you write out or draw out the square root of x.
00:08
So let's do that first.
00:10
That i hope you're well aware that you can only square root zero and positive numbers, square to zero is zero, square out of one is one, and then the square root of four is two.
00:22
And you could keep going, but i'm going to stop right there.
00:25
So that is what we would call the parent function.
00:29
And my thought process when i'm asked, do they name this, h of x, is equal to negative, sorry, the square root of negative x plus one.
00:42
What i like to do is take what's under the radical and set it greater than zero to find the domain.
00:51
I know it doesn't quite tell you to do this, but you would subtract one over.
00:56
And remember, when you divide by a negative, you have to flip that inequality.
01:00
So what's happening, and the reason why that helps me is that it's a y -axis reflection because it's opening to the left now...
