Chapter 3.1 - Exponential and Logistic Functions

• • See assigned homework for examples of types of questions you'll be asked

  • Given two pairs of point coordinates (x,y), write an exponential function y = a*b^x that passes through the two points. Your book a couple of these and we've also done these as "Do Now" in class. Remember that you can make up your own points, do the task, and then easily check on calculator. Remember to use "STO."

3-5 Newton's Law of Cooling

Watch before Day #68 lesson

Since our book has limited exercises on the topic, here are some additional Newton's Law of Cooling exercises from other textbooks if you need the practice. Solutions included on second page.

Also, here are the extra exercises used as classwork on this class day with worked-out solutions included. Remember, there are multiple ways to solve any of these exercises.

Even more Exponential/Logarithmic Equation exercises from another textbook

Here are some exercises and odd answers from another PreCalculus book (Larson, 7th ed).
