Answer:
1) 
2) 
3) 
Step-by-step explanation:
So we have the two functions: 

And we want to find (f+g)(x), (f-g)(x), and (f*g)(x). 
1) 
(f+g)(x) is the same to f(x)+g(x). Substitute: 

Combine like terms: 

Add: 

So: 

2) 
(f-g)(x) is the same to f(x)-g(x). So: 

Distribute: 

Combine like terms: 

Simplify: 

So:

3) 
(f*g)(x) is the same to f(x)*g(x). Thus: 

Distribute: 

Distribute: 

Combine like terms: 

Simplify: 

So:
