Can somebody help me with number 1. I am confused. Please Help. I will give Brainliest Answer.

I would say D is the correct answer. Take point C at (-1,1). To rotate 90 degrees about the origin, you change it to (1,1). Then to dilate by a factor of 2, you multiply both numbers by 2 and get (2,2). That give you point F and so the answer is D
