The video tutorial covers sketching graphs, focusing on exponential and logarithmic functions. It explains the inverse relationship between these functions and demonstrates how to sketch logarithmic graphs from exponential ones. The tutorial also explores various transformations of logarithmic functions, including reflections, translations, and stretches, providing a comprehensive understanding of graph transformations.
