Answer:
Reflection across y = 3.
Translation rightwards, 2 units
Step-by-step explanation:
To map triangle ABC onto triangle A''B''C'', we need to observe carefully the graph.
If you draw the libe y = 3, you would notice that triangle A''B''C'' is a reflection of the original triangle across y = 3, because the figure has the same shape and size, but reflected as a mirror, where the mirror is at y = 3.
Then, we move the triangle 2 units rightwards to map ABC onto A''B''C''.
Therefore, the sequence of transformations are
- Reflection across y = 3.
- Translation rightwards, 2 units
