Apply graph transformations in the correct order

Apply graph transformations in the correct order.

Translations change position, reflections change orientation and stretches change scale; the order matters when transformations are composed.

Worked example
y=2f(x−3) shifts right 3 then stretches vertically by 2.

Worked example
What does f(x−3) do? move the graph right 3, not left.

Common boundary
Inside changes act horizontally with reversed sign; outside changes act vertically.
