Overview
A composition of tramsformations involves 2 or more transformations applied to one shape or point. So, we do a transformation to get the 1st image, then we apply a 2nd transformation to that image to arrive at the final shape. It's much easier to understand with examples and demonstrations like on this page.
In this case, we 1st reflect the point over the line x-axis and then over the y-axis
In our demonstrations, we perform the right most reflection (x-axis) then the left one (y-axis). There is no correct way here so you have to check with your teacher to see if they go rigt to left, as we do; or left to right.
In this case, we 1st reflect the point over the line $$ y=x $$ and then over the x-axis
In this case, we 1st reflect the point over the line $$y=x$$ and then over the x-axis
