Which graph is the correct one?

Answer:
The upper graph
Step-by-step explanation:
We have two quadratic function here
[tex]y=-x^{2} +3x+5\\y=x^{2} +2x\\[/tex]
If we perform the function f(x) + g(x), which is nothing more than the sum of the two functions, we obtain a linear function, since the quadratic terms are eliminated by themselves
[tex]5x+5[/tex]
