Answer:
3x^2 -4
Step-by-step 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
[tex]\boxed{3x^2-4}[/tex]
[tex](f+g)(x)[/tex]
Rewrite.
[tex]f(x)+g(x)[/tex]
[tex](2x^2 +3)+(x^2-7)[/tex]
Combine like terms and simplify.
[tex](2x^2 +x^2 )+(3-7)[/tex]
[tex](3x^2 )+(-4)[/tex]
[tex]3x^2 +-4[/tex]
