Graphing and Analyzing Exponential Functions

The video tutorial covers exponential functions, including their graphing, analysis, and application in real-world problems. It explains how to use graphing calculators to plot exponential equations, identify key features like asymptotes, and derive equations from tables. The tutorial also addresses exponential regression using calculators to model data accurately.

What is the general form of an exponential function?

• y = ax^2 + bx + c

• y = a + bx

• y = a / b^x

• y = a * b^x
