Here we're given a function f of x, which is equal to one -fourth times x minus two squared minus five.
00:08
And we want to graph it.
00:10
So the first thing i'm going to do is note that this is a quadratic.
00:12
So it looks like this.
00:13
It's just a matter of how to place that thing there, the parabola.
00:17
It's a quadratic.
00:19
So the first thing i'm going to do is i'm going to find the vertex, which were shifted to the right to and go down five.
00:26
So 2 -n negative 5 is the vertex.
00:29
Right there.
00:31
And let's go ahead and find the vertex.
00:32
Intercepts because that'll help us find the rest of this.
00:35
So let's just set x equal to zero.
00:37
If x is zero, we have one -fourth times negative two squared is four minus five...
