What is the range of the function represented by these ordered pairs?

{(–2, 1), (0, 0), (3, –1), (–1, 7), (5, 7)}
{–2, –1, 0, 3, 5}
{–1, 0, 1, 7}
{–2, –1, 0, 1, 3, 5, 7}
{0, 1, 7}

{–1, 0, 1, 7}

Step-by-step explanation:

The range of the function is all of the y values of the points. In this case, that is 1, 0, -1, and 7. We don't have to list 7 twice. Therefore, the answer is {–1, 0, 1, 7}. Hope this helps!

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)
