Hey!
So (f+g)(x) is really just f(x) + g(x).
so now we know that we have to do:
4x + 7 + 3x^2 = (f+g)(x)
But wait! That's not in the right order. You have to put it in descending order like this:
3x^2 + 4x + 7 = (f+g)(x)
That's your answer
Hope this helps!

We have two equation we need to add together. We know to add them together because, it has f+g.

We have 4x+7+3x².
There are no like terms, so we need to put them in order of degrees.

3x²+4x+7=(f+g)(x) is the answer.

Tell me if this helps!!
