Question

Explain two ways you could evaluate (f + g)(2).

Answer 1

Well either you can add the 2 functions and then plug in 2 and then solve
Or You can plug in 2 and solve both equations separately and then add the 2 equations
So it wld look like f(2)+g(2)

Answer 2

I will give you an example
So let f(x)=1/x+3 and g(x)=x+2
#1 (f+g)(x)=(1/x+3)+(x+2)=1/x+x+5
Now lets plug in the 2
(f+g)(2)=1/2+2+5 = 15/2
#2 f(2)+g(2)=(1/(2)+3)+((2)+2)
= (7/2)+(4)
=15/2
