Help ASAP- I dont understand!!! Is the relation below a function? If it is a function, state its domain.

{(0,2),(2,4),(1,7),(2,5)}

A. The relation is not a function.
B. The relation is a function. The domain is {0,1,2}
C. The relation is a function. The domain is {2,4,5,7}
D. The relation is a function. The domain is {0,1,2,4,5,7}

A

Step-by-step explanation:

The relation is not a function. All you need to solve this problem is the following: Relations are NOT functions when the domain values repeat!

Note: The domain is the set of input values. The domain is x, the first number in the pair. For example, in the pair (0, 2), the domain is 0.

In the relation {(0,2),(2,4),(1,7),(2,5)}, 2 is repeated two times, which, by definition, means that the relation is not a function.

step-by-step explanation:

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
