Study Notes

Topic: Key Features of Exponential Functions

Domain, Range, and Intercepts

The domain of an exponential function is all real numbers.
The range of an exponential function is all positive real numbers.
The x-intercept of an exponential function is never reached.

Key Features

Exponential functions can show decay or growth.

End behavior of an exponential function can be organized.

Graphing Exponential Functions

Exponential functions can be graphed to show key features.
Graphing exponential functions can help identify key features.
Graphing exponential functions can help organize end behavior.

Real-World Applications

Exponential functions can model population growth, such as a colony of bacteria.
Exponential functions can model decay, such as the rate of decay of lions in a region.
Exponential functions can be used to make predictions and justify claims.
