PLEASE HELP: 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}

a² + b²= c²

24² + 7² = c²

c= 25

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
