I need help, I will Mark u as the brainiest answer!?

c

Step-by-step explanation:

it's not a function bc the x values have more than one y value between 1-3

“The X-values between 1 and 3 are paired with multiple y-values”

Step-by-step explanation:

If a graph has an x value, it can only have one y value or it is not a function. (must be a straight line to be a function).

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.
