Nick · Answer 1

C. a reflection across the x-axis, followed by counterclockwise rotation about the origin, and then a reflection across the x-axis

Step-by-step explanation:

Make use of a graph sheet divided into four quadrants, c ends up in the first quadrant, while other options end in the third quadrant.

Cale Mercado · Answer 2

I think its C because I just did all thew sequences on graph paper and C didn't match A B or D.
