UNIT 5
: EXPONENTIAL & LOGARITHMIC FUNCTIONS
LESSON 7: EXPONENTIAL
GROWTH AND DECAY
The following properties
of natural logarithms are important and used frequently in our study of
logarithms.
They correspond closely to
our previous rules for logarithms studied earlier.
Exponential Growth
and Decay Problems:
Growth and decay problems are governed by the following formula:
The half-life of a radioactive substance is the period of time a given amount will decay to half of it’s original amount.
