## 1-2 Composition of Functions

Function Operations

Composition of Functions

Domains of Composite Functions

### Lesson 1-2

Composition of Functions Essential Questions

• What are the 5 ways you can combine 2 functions?

• How do we solve a composite function?

Vocabulary

• Composition

• Composite

• Iterations

• Seed Value

c. (fg)(2)

d. (f+g)(0)

(f o g)(2)

### Inverse Functions:

• Given f(x) = x/3 +2, find the inverse of f(x), and show that the two functions are inverse functions.

• Two functions f and g are inverse functions if and only if [f o g] (x) = [g o f] (x) = x

### Domains of Composite Functions

• Find the domain of (f o g)(x) if

f(x) =

g(x) =
