Which would be the correct notation for the composition of transformations from blue to red to green?

• <-4,0> then R_{y axis}

• R_{y axis} then <0, -4>

• <0, -4> then R_{y axis}

Zach and Naomi are studying geometric transformations. Zach is able to move the triangle $A$ to  $A'$  using the following sequence of basic transformations:

        1. Reflection across the x-axis.
        2. Reflection across the y-axis.
        3. Translation two units to the right.
Naomi claims that the same three transformations, done in any order will always produce the same result. Zach disagrees. Who is correct?

• Zach

• Naomi

• Both are correct

• Both are incorrect
