Graph Transformations

You've learnt about three types of graph transformation - translations, stretches and reflections. 

You also learnt how to change coordinates when you're given the equation of a transformed function. The rule to remember is:

If the change is outside the brackets, only change the y-coordinates. For example for f(x) + 2, add two to the y-coordinates.

If the change is inside the brackets, only change the x-coordinates. Do the opposite of what it says.  For example for  f(x + 2), subtract two from the x coordinates.

This is an A* topic so if you understand it then well done! 

Have a go at the MyMaths homework - if you get stuck, try the lesson on MyMaths.

We'll look at graph transformations again when we study trigonometric graphs.
