Lesson 2a – Linear Functions and Applications Assessment 5. Use the equation found in problem 1 to predict the sales in 2015. Round your answer to the nearest tenth. 6. Interpret the meaning of the statement S(30) = 2.44. 7. Use the equation found in problem 1 to determine the year in which sales should reach $3,000,000. 8. Use your graphing calculator to generate a scatterplot of the data and regression line on the same screen. You must use an appropriate viewing window. In the space below, draw what you see on your calculator screen, and write down the viewing window you used.

Lesson 2b – Functions and Function Operations As we continue to work with more complex functions it is important that we are comfortable with Function Notation, opertions on Functions and opertions involving more than one function. In this lesson, we study using proper Function Notation and then spend time learning how add, subtract, multiply and divide Functions, both algebraically and when the functions are represented with a tables or graphs. Finally, we take a look at a couple of real work examples that involve operations on functions. Lesson Objectives: 1. Use proper FUNCTION NOTATION when reading, writing and working with functions and when performing OPERATIONS with functions. 2. Use a function to find INPUT given OUTPUT or find OUTPUT given INPUT 3. ADD and SUBTRACT functions by combining like terms 4. MULTIPLY or DIVIDE functions using rules of exponents 5. Perform OPERATIONS with functions using tables, graphs, or symbolic notation 6. Work with APPLICATIONS of function OPERATIONS (Cost, Revenue, Profit functions) Scottsdale Community College Page 73 Intermediate Algebra
