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
\((x,y)\rightarrow (-x,y)\)
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
\(R(-3,2)\rightarrow R'(3,2)\)
The coordinates of image of R are (3,2). Therefore the correct option is 4.
