Section 1. Logarithms. The mathematics of logarithms and exponentials occurs naturally in many branches of science. It is very important in solving problems related to growth and decay. The growth and decay may be that of a plant or a population, a crystalline structure or money in the bank.
Logarithms and Logarithmic 6.3 Functions. Essential Question. What are some of the characteristics of the graph of a logarithmic function? Every exponential function of the form f (x) bx, where b is a positive real number. = other than 1, has an inverse function that you can denote by g(x) = logb x.
Unit Overview. In this unit you will evaluate natural exponential and natural logarithmic functions and model exponential growth and decay processes. You will also solve logarithmic and exponential equations by using algebra and graphs.
