Objectives 

• Basic Graphs

• Special Bases

• Applications & Scientific Calculators

Examples

• Example 1

• Example 2

• Example 3

• Example 4

For example,

• a "linear function formula" contains the variable to the

first  power,  .
 
• a "quadratic function formula" contains the variable to the second power,  .

• a "polynomial function formula" contains the variable to various positive whole number powers,  .

For example, consider the functions: 

We call such functions "exponential functions."

We will answer many of the same questions that we have already answered concerning other types of functions.

Namely,  we will learn how to describe and graph exponential functions by identifying the domain, range, intercepts and asymptotes.

We will also learn how to "undo" an exponential function by using another special function called a "logarithm."
