What is the domain of the given function?

{(3, –2), (6, 1), (–1, 4), (5, 9), (–4, 0)}

a) {x | x = –4, –1, 3, 5, 6}
b) {y | y = –2, 0, 1, 4, 9}
c) {x | x = –4, –2, –1, 0, 1, 3, 4, 5, 6, 9}
d) {y | y = –4, –2, –1, 0, 1, 3, 4, 5, 6, 9}

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
