Answer:

In either order ...

  • A. Translation 3 units up
  • C. Reflection across y-axis

Step-by-step explanation:

The x-coordinates of the image are the opposite of the x-coordinates of the figure, so a reflection across the y-axis has occurred.

The y-coordinates of the image are 3 greater than the y-coordinates of the figure, so a translation upward by 3 units has occurred.

The translation upward and the reflection across the y-axis are independent transformations, so could occur in either order.

The answer could be A, C or C, A.

Answer:

A. Translation 3 units up

C. Reflection across y-axis

Step-by-step explanation:

reflect across y-axis mapping rule (x,y) > (-x,y)

translation k units up rule (x,y) > (x,y+k)
