Transformations of Exponential Functions

The video tutorial discusses the transformation of the natural exponential function. It guides viewers through sketching the curve of y = -4e^(-3x) by applying a series of transformations to the graph of y = e^x. These transformations include horizontal compression, reflection about the Y-axis, vertical stretch, and reflection about the X-axis. Each transformation is explained step-by-step, with viewers encouraged to apply these techniques to similar problems.
