The theme in this problem is another function notation and being able to identify ordered pairs.
00:06
So what's inside the parentheses is x.
00:09
And then the equals number is the, i guess, the y coordinate.
00:14
So as you look closely at this graph, i'll make the graph here in this color, i really don't care what's happening besides the x coordinates that they give me.
00:23
But it looks like, you know, we have an open circle here, down one left, so on and so forth.
00:29
And then it jumps all the way down to 1 negative 3 and then has kind of a goofy behavior.
00:47
But there's not a whole lot that i care about.
00:50
When i look at part a and they ask me to find f of negative 1, i just need to identify that when x was negative 1 on my graph, the y coordinate was 0.
01:03
So x was negative 1, y is 0.
01:06
So this answer would be zero...
