So the grass of two functions f and g are shown below.
00:08
I try to copy it as closely as possible to the actual picture you're posted.
00:13
And it says write a function formula for g using the function f.
00:18
So g of x equals what? then it says write a function formula for f using the function of g.
00:25
So if we're looking at this, these two functions, f and g are reflections over the x axis.
00:36
Because this point here and that point there line up, and this point here is the same as that point there, and this point here lines up with that one, and so on and so forth, all throughout both of the graphs.
00:50
And whatever this is, say it is a positive 2, well, this point, if the y value is a positive 2, so let's say that's at a negative 2, 2, then this point is a negative 2 and negative 2.
01:05
And here, that point is at 2 -2...
