So this question is giving me the function negative x squared plus nine, and it wants me to evaluate at negative 2, negative 1, 0, 1, and 2.
00:09
So the reason that most people have trouble with this is because of the negative on the outside.
00:15
So when i plug in, let's say for negative 2, it would be negative, negative 2 squared plus 9.
00:22
Well, negative 2 squared is 4, and then it would be negative 4 plus 9, which would be positive 5.
00:29
I'm going to do the same thing, but i'm going to plug it in for 1 now.
00:35
So negative 1 squared is positive 1, but times that negative in the beginning turns into a negative 1.
00:42
So this will be 8.

I'm going to do the same thing for 0...
