Answer:
Step-by-step explanation:
3a^4 -2a^2 + 5 - 10 -(2a^4 +4a^2 + 5a -2)
as given.. i'm wondering if the 5 in the first group is really 5a.. hmmm
I'm guessing that it is...  soooo distribute the minus sign 
= 3a^4 - 2a^2 +5a -10  -2a^4 -4a^2 -5a +2
= a^4 -6a^2 -8   :)  voila that's your answer

All you have to do for this is plug in each coordinate point to the function. Ex. (0,2). Plug in 0 to the “x” part of the function, and solve that side; you will get 2. Then you plug in 2 in this case for “y”. You will end up with 2<2 which is a FALSE statement. And you keep doing that until you get a TRUE statement.
