We're looking at f of x equals absolute value of x.
00:06
And when you change the equation to f of x equals absolute value of x plus two, or f of x equals absolute value of x minus two, since they are all absolute value functions, we call this a family of functions.
00:21
The question is, is what happens when we put a plus two after the original parent function or a minus two? so let's take a look at some graphs.
00:32
We want to look at the absolute value of the absolute value of x first.
00:42
And so here's our absolute value of x.
00:46
It starts at the origin, and we have a slope of 1 to the right.
00:51
We have an absolute value of slope of negative 1 to the left.
00:55
So this is your parent function of absolute value of x.
01:01
But what happens if we add two to the right hand side? so we've got absolute value of x and on the outside we're going to add two.
01:23
So if you'll notice we still have a slope of one.
01:28
And we know it's a slope of one without even looking at the grid because our blue graph, our parent function, is parent...
