O Decide if each set of ordered pairs or equation represents a function. Explain.
A. {(-4, 1), (3, 2), (-2, -1), (5,0), (-4,-1)}
B.{(-6, 3), (-5, 3), (-4,3), (-3, 3), (-2,3)}
C. y = x2 – 10
D. x2 + y2 = 25

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

a; x = 0.5

step-by-step explanation:

-10x = -5

x = 0.5
