What is the reflection image of R across the y-axis?

Answer:
The coordinates of image of R are (3,2). Therefore the correct option is 4.
Step-by-step explanation:
If a figure reflected across the y-axis, then
[tex](x,y)\rightarrow (-x,y)[/tex]
From the given figure it is clear that the coordinates of R are (-3,2). So, the reflection image of R across the y-axis is
[tex]R(-3,2)\rightarrow R'(3,2)[/tex]
The coordinates of image of R are (3,2). Therefore the correct option is 4.
