Reflections are another transformation we can use to alter the position of a function on a graph.
Graphical functions can be reflected to alter their position on a graph. This is like placing a mirror along one of the gridlines on the graph.
The plane of reflection is the line which acts as the mirror of a function. This can be any straight line on a graph.
Sometimes, we may want to reflect a single point. We can use what we know about reflections to help us find the new coordinates of the point once it has been reflected.
The effect of the transformation f(−x) is to..
We can also combine reflections with translations.
Under the transformation−f(x−4) , the point (3,4) would move to which point?
