Understanding Graph Transformations of Exponential Functions

The video tutorial explains how to match graphs to their corresponding functions by analyzing transformations of the function f(x) = e^x. It covers reflections across the Y axis, X axis, and both axes, demonstrating how these transformations affect the graph's appearance. The tutorial uses specific examples to illustrate each type of reflection and the resulting graph, helping viewers understand the impact of changing signs in the function's equation.
