Answer:
A(-3, 4) reflected across x-axis ==> A'(-3, -4)
A'(-3, -4) reflected across y-axis ==> A"(3, -4)
Graph attached
Explanation:
The point is (-3, 4) shown as point A on attached graph
When reflected across the x-axis to point A' the x-coordinate does not change but the y-coordinate is the negative of the original y-coordinate
Therefore A (-3, 4) ⇒ A' (-3, -4)
When A' is reflected across the y-axis to A" the x-coordinates change sign but y-coordinates stay unchanged
A'(-3, -4) ⇒ A" (3, -4)
So the final point is A"(3, -4)
