Explanation:
Ok, so what we need to do is add f(x) to g(x). like so:
Since is squared and x isn't, we can't add them.
But we can add the 4 and 2 and get this:
As far as I know, the domain is all real numbers.
Answer:
= -x^2 -x +6
D: all real values
f(x) = 4-x^2
g(x) = 2-x
f+g = 4-x^2+ 2-x
Combine like terms
= -x^2 -x +4+2
The domain is what values can x take
