Question

What is the imagine point of (4,-2) after the transformation ry=-i ○ D1/2

Answer 1

The image point of (4,-2) after the transformations given is; (2,1).

What is the image point after the transformations?

It follows from the task content that the point given is (4, -2) which first reflects over the y axis and hence, renders the new image to be; (4, 2) after which it undergoes a dilation of with dilation factor, 1/2 and hence, the image point is; (2,1).
