When you have y = f(ax), it has the effect of multiplying every instance of x by a factor of a. This results in a transformation of the graph of f(x) by stretching or squeezing the graph horisontally. If a < 1, the graph is stretched and it is squeezed if a > 1. If a<0, the graph is reflected about the x-axis.
