Answer:
A"(-6, 3)
B"(-9, 0)
C"(-5, -1)
Explanation:
We presume the first transformation is a translation 4 units right and 1 unit up:
(x, y) ⇒ (x+4, y+1)
The second transformation negates the x-coordinate, so the two transformations together have the rule ...
(x, y) ⇒ (-(x+4), y+1)
Then the transformed points are ...
A"(-6, 3)
B"(-9, 0)
C"(-5, -1)
