The video tutorial explains how to graph the function f(x) = x + 2 and its transformations. It covers shifting the graph vertically and horizontally, and the effects of multiplying the function by a negative number. The tutorial provides both graphical and algebraic perspectives, demonstrating how these transformations affect the slope and intercept of the line.
