Question

Can I please get help?

Answer 1

`\boxed{3x^2-4}`

Explanation:

`(f+g)(x)`

Rewrite.

`f(x)+g(x)`

`(2x^2 +3)+(x^2-7)`

Combine like terms and simplify.

`(2x^2 +x^2 )+(3-7)`

`(3x^2 )+(-4)`

`3x^2 +-4`

Answer 2

3x^2 -4

Explanation:

f(x) = 2x^2 +3

g(x) = x^2 -7

(f+g) (x) = 2x^2 +3 + x^2 -7

Combine like terms

= 3x^2 -4
