Question 312917: If f(x)=x^2+3x+1 and g(x)=2x+5, then (f+g) (x) equals what?
Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!
Just add like terms:
(x)\ =\ f(x)\ +\ g(x)\ =\ x^2\ +\ 5x\ +\ 6)
That is if you actually meant (x))
and not (x))
which is the composition of functions and totally different than their sum. Let me know.
