Lesson 2b <strong>–</strong> Functions and Function Operations<br />

As we continue to work with more complex functions it is important that we are comfortable<br />

with Function Notation, opertions on Functions and opertions involving more than one function.<br />

In this lesson, we study using proper Function Notation and then spend time learning how add,<br />

subtract, multiply and divide Functions, both algebraically and when the functions are<br />

represented with a tables or graphs. Finally, we take a look at a couple of real work examples<br />

that involve operations on functions.<br />

Lesson Objectives:<br />

1. Use proper FUNCTION NOTATION when reading, writing and working with<br />

functions and when performing OPERATIONS with functions.<br />

2. Use a function to find INPUT given OUTPUT or find OUTPUT given INPUT<br />

3. ADD and SUBTRACT functions by combining like terms<br />

4. MULTIPLY or DIVIDE functions using rules of exponents<br />

5. Perform OPERATIONS with functions using tables, graphs, or symbolic notation<br />

6. Work with APPLICATIONS of function OPERATIONS (Cost, Revenue, Profit<br />

functions)<br />
