Transformations of Exponential Functions

The video tutorial covers transformations of exponential functions, including translations, reflections, and dilations. It explains how these transformations affect the graph of a function on a coordinate plane. The tutorial provides examples to illustrate vertical and horizontal movements, reflections, and stretches or compressions. By the end, students should understand how to identify and describe these transformations.

What happens to an exponential function when a number is subtracted from the exponent?

• The graph moves down.

• The graph moves up.

• The graph moves right.

• The graph moves left.
