Key Concepts

Exponential Functions

Exponential functions are mathematical expressions where a constant base is raised to a variable exponent. They exhibit growth or decay depending on whether the base is greater than 1 or between 0 and 1, respectively, and are fundamental in modeling natural processes such as population growth and radioactive decay.

Graph Transformations

Graph transformations involve shifting, stretching, compressing, or reflecting the basic graph of a function. For exponential functions, adding a constant outside the exponential term translates the graph vertically or horizontally. This process allows you to modify standard graphs and understand how changes to the function's equation influence its shape and position.

Domain and Range

The domain of a function consists of all the input values for which the function is defined, while the range consists of all the output values the function can produce. In the context of exponential functions, the domain is typically all real numbers, and the range is often restricted to positive values, although vertical shifts can modify this range.

Horizontal Asymptote

A horizontal asymptote is a horizontal line that the graph of a function approaches as the input variable goes to positive or negative infinity. For exponential functions, the horizontal asymptote represents a limit of the function’s value and is particularly important when the function is transformed, as it indicates the value that the function will never actually reach but gets arbitrarily close to.
