Answer:
D
Step-by-step explanation:
The question firs states that the points are moved three points upwards. This means that each point has an increase of the y value by three points.
This gives us the points (0,4), (4,3) and (4,-4)
Reflecting them across the y-axis, it means that their height will stay the same. but the x value will be on the other side of the x- axis.
This leaves us with the answer D.
Note that the first point stays the same because it is on the y-axis, it doesn't get reflected.
Hope this helps.
