Which step of ordered pairs represents a function? a) {(2,-2), (1, 5), (-2, 2), (1,-3), (8,-1)}b) {(3, -1), (7, 1), (-6,-1), (9,,-1) c) {(6, 8), (5, 2), (-2,-5), (1,-,9)d) {(-3, 1), (6, 3), (-3,2), (-3,-,-1)

B

Step-by-step explanation:

A function does not have 2 of the same x values that have different y values.

An example of a function: (5,5) (4,5)

Not an example of a function: (5,5) (5,7)

Basically, if there's two points with the same x value, but different y values. However, two points with different x values but the y value can still be considered a function.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
