The video tutorial from Versus Math Club introduces the concept of nonlinear functions, contrasting them with linear functions. It explains that linear functions follow the formula y = MX + B, where M is the slope and B is the y-intercept. The video details how to determine if a function is linear or nonlinear by examining the slope. If the slope remains constant, the function is linear; if not, it is nonlinear. The tutorial also covers how to identify patterns in X and Y coordinates to determine the slope, concluding that varying slopes indicate a nonlinear function.
