The video tutorial explains how to use the graph of a function, f(x), to determine specific function values and graph its inverse. It demonstrates finding f(1) graphically and explains the process of plotting the inverse function on the same coordinate plane. The tutorial also covers calculating the derivative of the inverse function, emphasizing the relationship between the slopes of tangent lines on the function and its inverse. Key concepts include graph analysis, inverse functions, and derivative calculations.
