If f(x) = 3x2 - 1 and g(x) = x+2, find (f+g)(x)

3x^2 + x + 1

Step-by-step explanation:

(f+g)(x) just wants you to add f(x) and g(x) together.

If f(x) = 3x^2 - 1 and g(x) = x + 2, you can add them together like so:

(3x^2 - 1) + (x + 2)

Combine like terms and add -1 and 2 together.

3x^2 + 1 + x

Rewrite this expression so it is in standard form (the exponents are in order from greatest to least).

3x^2 + x + 1
