# Algebra II Chapter 4

• Objectives: (Chapter 4)

LESSON 4.1/2: CC.9-12.F.IF.7 Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases.

e. Graph exponential and logarithmic functions, showing intercepts and end behavior, and trigonometric functions, showing period, midline, and amplitude.

 Wed 01/03/18 Lesson 4.1-2 overview Read 4.1-2 If a > 0 and b > 1, then the function y = abx is an exponential growth function, and b is called thegrowth factor. You will graph exponential growth functions in the form y = bx, y = abx, andy = abx – h + k for b > 1. You will find compound interest and account balances using thecompound interest equation. If a > 0 and 0 < b < 1, then the function y = abx is an exponential decay function, and b is called thedecay factor. You will graph exponential decay functions in the form y = bx, y = abx, andy = abx – h + k for 0 < b < 1. Examples of Exponential Growth/Decay Domain/Range Graphing Exp Growth.
