Question

Advance Algebra: please help!

Answer 1

Explanation:

Ok, so what we need to do is add f(x) to g(x). like so:

`(4-x^2)+(2-x)`

Since
`x^2` is squared and x isn't, we can't add them.

But we can add the 4 and 2 and get this:

`-x^2-x+6`

As far as I know, the domain is all real numbers.

Answer 2

= -x^2 -x +6

D: all real values

Explanation:

f(x) = 4-x^2

g(x) = 2-x

f+g = 4-x^2+ 2-x

Combine like terms

= -x^2 -x +4+2

= -x^2 -x +6

The domain is what values can x take

D: all real values
