Question

1. which describes the transformation shown below? a. reflection over the y - axis b. rotation 270° clockwise c. rotation 90 ° clockwise d. translation left

Explanation:

Step1: Recall transformation definitions

Reflection over y - axis changes sign of x - coordinates. Rotation changes orientation. Translation moves shape without rotation or reflection.

Step2: Analyze the transformation

The shape A is flipped across the y - axis to get A'. In a reflection over the y - axis, if a point (x,y) in shape A has coordinates, its image (x',y') in A' has x'=-x and y' = y. This matches the transformation shown.

Answer:

A. Reflection over the y - axis
