In this question, we are going to be graphing the given sign function.
00:08
There is no phase shift because my argument is one -half -x, nothing added or subtracted.
00:16
So there's my vertical axis.
00:21
There is no vertical shift.
00:24
So my midline is the x -axis.
00:31
My amplitude is the absolute value of the leading coefficient.
00:36
So i will go two spaces above and two spaces below the midline.
00:44
Now let's set the argument, 1 half x equal to 0 pi and 1 half x equal to 2 pi.
00:56
I use 0 pi and 2 pi because those are the beginning and end of one phase of the parent function.
01:03
Let's solve for x.
01:05
Multiply both sides by 2 over 1...
