You really have to focus on the outputs if the input is negative 2.
00:05
So the output on function g, when the input's negative 2, you get an output of negative 1 according to the graph.
00:16
And on function f with an input of negative 2, you get an output of negative 8.
00:23
So when you think of f plus g of negative 2, you need to think of this as f of negative 2 plus g of negative 2.
00:32
F of negative 2 is the negative, well, actually i have that backwards.
00:41
F of negative 2 is technically negative 8.
00:46
G of negative 2 is technically negative 1.
00:48
I have those backwards, but the output is the same.
00:52
Negative 9.
00:54
F minus g of negative 2 is f of negative 2 minus g of negative 2, which would be f of negative 2, which is negative 2, minus g of negative 2, which is negative 1.
01:05
Negative 8 minus negative 1 is negative 8 plus 1 or negative 7...
