Investigate the behavior of the function as n or $x$ grows large by making a table of function values and plotting a graph (see Example 4 ). Describe the behavior in words.
$$f(x)=\left(\frac{x+6}{x-4}\right)^{x}$$

Key Concepts

Exponential Functions

This concept involves functions where the variable appears in the exponent, leading to rapid changes depending on the interplay between the base and the exponent. Understanding exponential behavior is essential when analyzing how small changes in either component can result in significant variations in the function's output.

Asymptotic Behavior

This concept describes how a function behaves as the variable grows arbitrarily large or approaches critical points. It involves the analysis of trends such as convergence to a limit, growth toward infinity, or approach to asymptotes, which are crucial for predicting long-term behavior.

Limit Evaluation

Limit evaluation is the process of determining the value that a function approaches as the independent variable tends to infinity or a particular point. In functions involving a variable exponent, limits help to simplify and understand the overall behavior by identifying convergent or divergent trends.

Graphical Analysis

Graphical analysis entails plotting the function over a range of values to visualize trends like increases, decreases, and asymptotic behavior. It provides a clear representation of how the function behaves for large inputs and complements analytical methods to better understand the function's long-term behavior.

Table of Values

Creating a table of function values is a practical approach for manually observing how a function changes with varying inputs. This method helps to validate analytical predictions, reveal trends, and provides concrete numerical examples that facilitate a deeper understanding of the function's behavior.
