With analysis, the first piece of this piecewise function is upside down forabola.
00:08
The vertex is at 1, 2.
00:10
And so in vertex form, we know it would be x minus 1 squared plus 2.
00:18
It's upside down, so there'd be a negative in front of it.
00:23
And you could test it out.
00:25
Like if x is 1, then we get 1 minus 1 is 0 squared as 0 plus 2 is 2.
00:32
You could test negative 1, negative 2.
00:34
Negative 1 minus 1 is negative 2 squared as 4, negative 4 plus 2 is negative 2.
00:39
So this is your first piece...
