Okay, so we're going to refer to the graph in the textbook to answer parts a through n.
00:07
So part a, find f of 0.
00:15
So the function where x equals 0, y equals 3, and the function where x equals negative 6 is equal to negative 3.
00:35
So that's part a.
00:40
For part b is f of 3 negative or positive.
00:47
So f of 3 is equal to, well, we know f of 2 is equal to 4 and f of 4 is equal to 3.
01:04
So this is positive.
01:08
Part c.
01:13
Oh, sorry.
01:15
This was part c.
01:17
So part b is to find f of 6, so x equals 6, y equals 0, and f of 11, so when x is equal to 11, y is equal to 1.
01:37
So for part d, is f of negative 4, positive, or negative...
