Why does y=-f(x) and y=f(-x) reflect y=f(x)
in the x-axis and y-axis respectively?
Being able to transform basic graphs is an essential skill to develop for sketching graphs. In this series of videos I show you why various transformations work on any graph of the form y = f(x).
Other videos in this series of Why they do what they do? are : translations, stretches
