Which set of ordered pairs represents a function?
a. {(0, 1), (1, 2), (2, 3), (3, 3)}
b. {(0, 1), (1, 2), (1, 3), (2, 5)}
c. {(0, 0), (1, 2), (2, 4), (2, 6)}
d. {(0, 0), (0, 1), (2, 0), (2, 4)}

A

Step-by-step explanation:

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
