1. Which one of the following ordered pairs does
NOT define a function?
A (5,5.5), (8, 7.5), (10, 8)
B (-2, -6), (0, – 7), (2, -8)
C (-2, 4), (-1, 2), (6, 42)
D (6,2), (6,5), (7,21)

d

Step-by-step explanation:

each input can only have one output

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3
