I believe the answer is.
5x^2 + 6x - 1
                                
             
                    
              
              
                
                
f(x) is a fancy way of saying y. So for now I will refer to y.
f(x)
y=3x+2+7x
g(x)
y=2x2-x-1
3x+2+7x+(2x2)-x-1 = f(x)+g(x)
Now lets add
10x+2+4-x-1=f(x)+g(x)
9x+5=f(x)+g(x)
