Can I please get help?

Answer 1

Answer:

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

Step-by-step 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

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
