Answer:
5
Step-by-step explanation:
(f+g)(2) means f(2)+g(2).
f(2) means to evaluate the expression called f at x=2.
So f is x+1 and it wants us to plug in 2 for x.
x+1 with x=2
2+1
3
This means f(2)=3, f(2) has value 3.
g(2) means to evaluate the expression called g at x=2.
So g is x^2-x and it wants us to plug in 2 for x.
x^2-x with x=2
2^2-2
4-2
2
This means g(2)=2, g(2) has value 2.
Let's go back to (f+g)(2).
(f+g)(2)=f(2)+g(2)
(f+g)(2)= 3 + 2 (I replaced f(2) with 3 and g(2) with 2).
(f+g)(2)=5
