Hello!

The correct answer is A translation 3 units up then a reflection across the x-axis.

Translation: moving/sliding a figure
Reflection: taking a figure and flipping it over a line.

Answer:  

translation 3 units down then a reflection across x-axis

Step-by-step explanation:

  • A translation is a kind of rigid motion . It trace a function that maps an object a particular distance.
  • A reflection is a kind of rigid motion . It is mainly a flips of a shape across the line of reflection.

In the given figure, we can see that Δ ABC is vertically 3 units away from the x axis .

So we translate  Δ ABC by 3 units down and then reflect it across x axis to get ΔDEF.
