Which of the following relations is not a function?

a. {(2, 6), (- 4, 0), (2, 2), (3, 5)}
b. {(0, 0), (10, 4), (- 8, -5), (1, 1)}
c. {(12, 0), (- 4, 6), (2, 3), (6, 6)}
d. {(1, - 6), (9, 5), (7, 7), (5, 3)}

It is A.

Step-by-step explanation:

In function A we see that there are 2 ordered pairs with value 2 in the first position with y values 6 and 2. So this is not a function.

the answer is a

step-by-step explanation:

because your just changing the position of where the shape is

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
