The range of the following relation r {(3, −2), (1, 2), (−1, −4), (−1, 2)} is a: {−1, 1, 3} b: {−1, −1, 1, 3} c: {−4, −2, 2, 2} d: {−4, −2, 2}

D: {−4, −2, 2}

Step-by-step explanation:

The range in this case is the set of all the y-values of the ordered pairs.

In listing the elements in the range, we do not list an element more than once, even though it may appear multiple times in the ordered pairs.

Therefore the range is

D: {−4, −2, 2}

D: : {−4, −2, 2}

Step-by-step explanation:

well what did you do it matters what you did : )

step-by-step explanation:

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
