A function is asymptotic to a given line if the given line is an asymptote of the function.
An exponential function is a function whose variable is in the exponent. The general form is .
grows without bound
If a function grows without bound, it has no limit (it stretches to ).
A horizontal asymptote is a horizontal line that indicates where a function flattens out as the independent variable gets very large or very small. A function may touch or pass through a horizontal asymptote.
Transformations are used to change the graph of a parent function into the graph of a more complex function.
Graph an exponential function and compare graphs of exponential functions on the same graph.
