  1. Bell Work 4/2/2015 • Write in FULL SENTENCES 3 things you will accomplish over Spring Break. • Bell Work Log DUE TODAY!!!!

  2. ExponentialGrowth   » Extension Lesson

  3. Today’s Objective: • How are linear functions (prior knowledge) and exponentialfunctionsalike/different? • What are someways to describe, create, and evaluatethese graphs? • How doesexponentialgrowthconnect to real life?

  4. Warm-Up You have won the Math Lottery! You have payment options: Wouldyouratherreceive one cent on Day 1, double that, or two cents on Day 2, and so on, doublingyourpaymenteveryday for the next 30 days, or exactly $1,000,000 up front? 1 minute – GO!

  5. Cool Fact:All exponential growth functions look like this! What does Exponential Growth look like? Table of Values: Consider y = 2x

  6. Example: You deposit $1,500 in an account that pays 6% annual interest. Find the balance after 5 years if the interest is compounded: a. Quarterly. b. Monthly. P = 1500 t = 5 r = 0.06 a. n = 4 b. n = 12 = $2020.28 = $2023.28

  7. Cool Fact:All exponential decay functions look like this! What does Exponential Decay look like? Consider y = (½)x Table of Values:

  8. Class Work • Complete the Exponential Growth/Decay worksheet • Worksheet is due at the end of class today!!!!! • Have a great Spring Break
