The video tutorial explains how to graph the exponential function y = 2^x and the logarithmic function y = log base 2 of x on the same coordinate plane. It demonstrates graphing by hand using a table of values, highlighting the exponential growth and horizontal asymptote of the exponential function, and the vertical asymptote of the logarithmic function. The tutorial also discusses the inverse relationship between the two functions, showing their symmetry across the line y = x.

What is the main goal of graphing the exponential and logarithmic functions together?

• To determine their maximum values

• To discuss their inverse relationship

• To compare their growth rates

• To find the intersection points
