help me with f(x)=3x+1 please

Question

Let f(x)=3x+1, g(x)=x+3, and h(x)=3x^2+10x+3. Write a formula for each of the following functions

 

 (f+h)(x)=

(h−g)(x)=

(f+g+h)(x)

 

(h−g)(x)=

 

 

 

f.

 

(f+g+h)(x)

Answer 1

f = 3x+1

g = x+3

h=3x^2 +10x + 3

h-g = 3x^2 +9x

f+h = 3x^2 +13x +4

f+g+h = 3x^2 +14x + 7
