Lesson 4a – Introduction to Logarithms Assessment 4. Solve the following equations. Show your work. Simplify your answers. Leave your answers in exact form (no decimals). a) log 3 x 5 b) 2 log 4(2x 1) 5 c) 8 2log 7 x 10 d) 3log(7 x 1) 6 Scottsdale Community College Page 160 Intermediate Algebra
Lesson 4b – More on Logarithms This lesson will begin with a review of exponential and logarithmic forms for equations, as we will switch back and forth from one form to the other when solving equations. You will learn the all-important “change of base formula” next. This formula allows you to easily compute logarithms that have bases other than 10 and use your calculator to do so. The lesson will end with an exploration of the graph of logarithmic functions and their characteristics followed by modeling of data sets with Logarithmic Regression. This lesson ends our tour of logarithms and exponential functions as we will next be moving on to quadratic functions. Lesson Objectives By the end of this lesson, you should be able to: 1. Discuss the concept of LOGARITHMS as EXPONENTS 2. Compute LOGARITHMS of bases other than 10 3. Compute LOGARITHMS using the CHANGE OF BASE formula and a calculator 4. Solve EXPONENTIAL EQUATIONS algebraically and graphically 5. Graph f(x) = log b x and identify important characteristics 6. Determine if a given data set can be well modeled by a LOGARITHMIC FUNCTION 7. Use LOGARITHMIC REGRESSION (natural logarithm) to model a given data set Scottsdale Community College Page 161 Intermediate Algebra
