Study Notes
Exponential Functions and Equations
- Exponential functions are used to model real-world problems, including growth and decay.
- The general form of an exponential function is f(x) = ab^x, where b is a rational number.
- The values of a and b in an exponential function have specific meanings in real-world problems.
- The domain and range of exponential functions can be determined and represented using inequalities.
- Graphing exponential functions helps identify key features, such as y-intercept and asymptote.
- Technology can be used to write exponential functions that provide a reasonable fit to data and make predictions for real-world problems.
- Exponential functions can be used to describe problems arising from mathematical and real-world situations.
Key Features of Exponential Functions
- Y-intercept: the point where the graph crosses the y-axis.
- Asymptote: the line that the graph approaches as x increases or decreases without bound.
Real-World Applications
- Exponential functions can be used to model growth and decay in real-world situations.
- Examples of real-world problems that can be modeled using exponential functions include population growth, chemical reactions, and financial transactions.
