All right, welcome back.

So for this problem, more graphing functions, y is equal to tangent of x plus 4, or pi over 4, and y is equal to, oops, negative tangent of x plus pi over 4.
00:22
All right, so these two functions are two trigonometric functions.
00:29
And so they have periodic, they're periodic, right? so that means that they repeat over and over and over again as you increase or decrease in values of x.
00:41
So in the case of tangent in general, it's going to look like, oops, it's going to look something like that, where this right here, there's a nassumptop at pi over 4, an negative pi, oops, pi over 2, i mean, and negative pi over 2.
00:59
And so it's going to, yeah, i'm going to keep repeating that.
01:06
All right.
01:06
So if we're going to grab these, then that is a horizontal shift right there of pi over four.
01:18
So it goes pi over four backwards...
