Answer:


(f+g)(x)=3x^2+(3)/(2) x-9

agreeing with answer C in your list.

Explanation:

If
f(x)=(x)/(2) -3 and
g(x)=3x^2+x-6 then the addition of the functions would be:


(f+g)(x)=g(x)=(x)/(2) -3+3x^2+x-6=3x^2+(3)/(2) x-9

Hey there! :)

Answer:

C. (f + g)(x) = 3x² + 3x/2 - 9

Explanation:

(f + g)(x) requires you to add functions f(x) and g(x) together. Therefore:

(f + g)(x) = x/2 - 3 + 3x² + x - 6

Combine like terms:

(f + g)(x) = 3x² + x + x/2 - 3 - 6

Simplify:

(f + g)(x) = 3x² + 3x/2 - 9

Therefore, the correct answer is C.
