Lesson 20 Exponential Growth & Decay Applications Made Easy | Algebra 1 | Regents Review

Welcome back to Math and Engineering Made Easy! In this Algebra 1 Lesson 20, we continue our study of exponential functions by exploring real-world applications involving growth and decay. We learn how to identify the parts of an exponential function, understand the meaning of the initial value, growth/decay factor, and number of time periods, and apply these concepts to problems similar to those found on the Algebra 1 Regents Exam. This lesson focuses on recognizing whether a situation represents exponential growth or exponential decay and how to interpret the meaning of each part of an exponential equation. 📚 Topics Covered ✅ Standard Form of an Exponential Function ✅ Initial Value and Final Value ✅ Growth Factor vs. Decay Factor ✅ Identifying Growth from the Multiplier ✅ Identifying Decay from the Multiplier ✅ Finding Percent Growth Rate ✅ Finding Percent Decay Rate ✅ Interpreting Exponential Models ✅ Savings Account Applications ✅ Population Growth and Decay ✅ Appreciation and Depreciation ✅ Real-Life Exponential Models ✅ Regents-Style Multiple Choice Problems ✅ Comparing Linear vs. Exponential Change This lesson builds the foundation needed for graphing exponential functions, solving exponential equations, and understanding logarithmic functions. 👍 If this lesson helps you, please Like, Subscribe, and Share to support Math and Engineering Made Easy! #Algebra1 #ExponentialFunctions #ExponentialGrowth #ExponentialDecay #MathTutorial #RegentsMath #LearnAlgebra #AlgebraHelp #HighSchoolMath #SATMath #STEMEducation #MathExplained #GrowthAndDecay #ExponentialModels #MathAndEngineeringMadeEasy
