The video tutorial covers exponential functions, focusing on graphing y = 3^x and y = (1/4)^x using Desmos. It explains how to plot points on the graph and highlights the behavior of these functions. The tutorial also discusses the domain and range of exponential functions, emphasizing that the domain includes all real numbers while the range consists of positive numbers only.

What is the base of the exponential function discussed in the first example?

• 4

• 3

• 2

• 5
