Lesson 4b – More on Logarithms Assessment 2. Use a graphing calculator to estimate the value of the following expressions. Round your answers to three decimal places. a) log5 37 b) log3 108 3. Solve for x. Where applicable, give both the exact answer and the decimal approximation rounded to three decimal places. Show your work. a) 5 log 2( x 8) 5 b) 1000(1.12) x = 2000 Scottsdale Community College Page 182 Intermediate Algebra
Lesson 5a – Introduction to Quadratic Functions We are leaving exponential and logarithmic functions behind and entering an entirely different world. As you work through this lesson, you will learn to identify quadratic functions and their graphs (called parabolas). You will learn the important parts of the parabola including the direction of opening, the vertex, y-intercept, and axis of symmetry. You will use graphs of quadratic functions to solve equations and, finally, you will learn how to recognize all the important characteristics of quadratic functions in the context of a specific application. Even if a problem does not ask you to graph the given quadratic function or equation, doing so is always a good idea so that you can get a visual feel for the problem at hand. Lesson Objectives By the end of this lesson, you should be able to: 1. Identify QUADRATIC FUNCTIONS and list their characteristics 2. Graph a QUADRATIC FUNCTION and determine direction of opening, vertex, axis of symmetry, y- intercept, x-intercepts. 3. Solve QUADRATIC EQUATIONS by graphing 4. Solve applications involving QUADRATIC FUNCTIONS Scottsdale Community College Page 183 Intermediate Algebra
