In Exercises, let ABCD be the square with vertices (- 1, 1), (1, 1), (1, - 1), and (- l, - 1). Use the result in Exercises to find and draw the image of ABCD under the given transformation.
a. T in Exercise 3

In Exercise 17, 18 show that the given transformation from R2 to R2 is linear by showing that it is a matrix transformation.
b. D in Exercise 17 D stretches a vector by a factor of 2 in the x-component and a factor of 3 in the y-component.
c. P in Exercise 18 P projects a vector onto the line y = x
