Understanding Exponential and Logarithmic Functions

The video tutorial explains how to match graphs to their corresponding equations, focusing on exponential and logarithmic functions. It covers the properties of exponential growth, the relationship between exponential and logarithmic functions, and how to identify inverse functions. The tutorial also discusses the graphical representation of these functions and their symmetry across the line y = x.

• y = 10^x

• y = x^2

• y = x^10

• y = log x
