Honors Algebra II with Trigonometry Mr. Agnew Function Operations

Essential Question Essential Vocabulary How do you perform operations on functions? Essential Vocabulary Function Function Composition Domain

Review: Domain of a Function The domain of a function includes all of the values that can be plugged into x. 1. Linear Functions: 2. Quadratic Functions:

Review: Domain of a Function 3. Special Power Functions a) b)

Operations on Functions Adding/Subtracting functions combine like terms Multiplying functions FOIL or distribute functions Divide functions Cancel like terms on top and bottom of fraction (you may have to factor)

Composition of Functions One function is the input of another function. Plug the “inside” function into x of the “outside” function.
