family of graphs. vertical dilation (stretch) g(x) = a · f(x) if a > 1. is the graph of vertical dilation f(x) – (compression) if 0 < a < 1. horizontal dilation g(x) = f(ax) (compression) if a > 1. Dilations is the graph of f(x) horizontal dilation – (stretch) if 0 < a < 1. Transformational Graphing Linear functions g(x) = x + b
