Answer:
A. Dilation by a scale factor of 1/2 followed by reflection about the x-axis
Explanation:
1/2 × P(-4,2)=(-2,1),
1/2 × Q(0,0)=(0,0),
1/2 × R(2,6)=(1,3).
d = 1/2.
(-2, 1) ⇒ P'(-2, -1),
(0, 0) ⇒ Q'(0, 0),
(1, 3) ⇒ R'(1, -3).
This is a reflection over X-axis.
Therefore, the set of transformations is given by
Dilation by a scale factor of fraction 1 over 2 followed by reflection about the x-axis.
