Assume that T is a linear Transformation.

a) Find the Standard matrix of T is T: R2 -> R3 first rotate point through (pie)/2 radian (counterclock-wise) and then reflects points through the horizontal x-axis

b) Use part a to find the image of point (1,1) under the transformation T

Please explain as much as possible. This was a past test question that I got no points on. I'm study for the final and am trying to understand past test questions.
