Question

i dont get I'm confused so much right know it would really help if you guys knew the answer

Answer 1

Answer: C.

Step-by-step explanation:

The question is simply asking you to find a new function ((f+g)(x)) which is represented by adding f(x)+g(x) and simplifying.

So first, set up the addition.

$(f+g)(x)=\frac{x}{2} -3+4x^{2} +x-4$

Now, combine like terms and rearrange in order of descending powers.

$(f+g)(x)=4x^{2} + \frac{3}{2}x-7$

This corresponds to answer C., the correct answer.
