Okay, so number 15, we have f of x equals x squared.
00:07
Now, the first thing you want to do is find your vertex.
00:10
Whatever makes this be zero is your vertex x.
00:14
Whatever's being added over here, in this case, zero is the y in vertex.
00:19
So this is starting at the origin.
00:21
And then we want to go left and right.
00:22
So i'm going to go negative 1 squared equals 1.
00:28
So that gives me the point.
00:29
I put a negative 1 in for x.
00:32
And i got a positive 1 for 1.
00:34
I'm going to go 1 the same distance to the right, which is 1...
