Lesson 1: Properties and Graphs of Exponential Functions ... Be ready to ask questions tomorrow. ... Oct 06, 2020 · The properties of logarithms allow you to solve logarithmic and exponential equations that would be otherwise impossible. These only work if the base a and the argument are positive. Also the base a cannot be 1 or 0. The properties of logarithms are listed below with a separate example for each one with numbers instead of variables.

The semester exam is going to 40 Multiple Choice questions and 6 Free Response questions covering Units 1-6. If you complete and understand this review packet then you will do very well on the exam. Check out the review videos for each chapter for a quick refresher. The math robot says: Because they are defined to be inverse functions, clearly $\ln(e) = 1$ The intuitive human: ln(e) is the amount of time it takes to get “e” units of growth (about 2.718). But e is the amount of growth after 1 unit of time , so $\ln(e) = 1$.

Apr 11, 2018 · 1. Definitions: Exponential and Logarithmic Functions. by M. Bourne. Exponential Functions. Exponential functions have the form: `f(x) = b^x` where b is the base and x is the exponent (or power). If b is greater than `1`, the function continuously increases in value as x increases. Logarithms are the inverses of exponents. They allow us to solve hairy exponential equations, and they are a good excuse to dive deeper into the relationship between a function and its inverse.
