This video tutorial covers the graphing of logarithmic functions, focusing on understanding their relationship with exponential functions. It explains how to graph these functions without a calculator, discusses their properties such as domain, range, and asymptotes, and demonstrates transformations including horizontal and vertical shifts. The tutorial also explores advanced graphing techniques for logarithmic functions with different bases and introduces natural logarithms.

What is the relationship between exponential and logarithmic functions?

• They are both linear functions.

• They are the same.

• They are inverses of each other.

• They are unrelated.

What happens to the domain of a logarithmic function when it is the inverse of an exponential function?

• It becomes the range of the exponential function.

• It remains the same.

• It becomes negative.

• It becomes zero.
