Introduction to Exponential and Logarithmic Models

LEARNING OBJECTIVES

By the end of this lesson, you will be able to:
  • Model exponential growth and decay.
  • Use Newton’s Law of Cooling.
  • Use logistic-growth models.
  • Choose an appropriate model for data.
  • Express an exponential model in base e.
