Arithmetic Combinations of Functions

Arithmetic Combinations of Functions, Composition of Functions

There are 5 types of arithmetic combinations of functions but we have only been taught 4 as of now. The 4 are sum, difference, product, and quotient.

Sum
(f+g)(x)= f(x) + g(x)

Ex:    

           
             

Difference
(f-g)(x)= f(x) - g(x)

Ex:
   

             
           
              

                  
Product
(f*g)(x)= f(x) * g(x)

Ex:
     
 
            
           
           

Quotient 
 

Ex:

(f+g)(3) = 0 + (-2) = -2

(f-g)(-5) = -2 - 4 = -6
