Which relation is a function?

2 answers:

5 0

The second option because one same input cannot have two different outputs
For example, x + 2 = y
If I put in 3, y has to equal 5, nothing else.
This makes the second option the only option that is a function
Hope this helps!

Answer:

The second one

Step-by-step explanation:

In a function an input has a distinct output, so if I put 3 into a function and got 8, that is my answer and nothing else, if I put 3 again and get -2 then it isn't a function because I got a different answer. In the 1st, 3rd and 4th one there are two outputs for the same input so they aren't functions.

The width of a rectangle is 2 meters less than its length, and the perimeter is 32 meters. Find the length and width of the rect

cupoosta [38]

The perimeter is equal to 2(width) + 2(length). let's call the width w and the length L.

so 32 = 2w + 2L
the width is given as 2 meters less than the length, so w = L - 2

32 = 2(L - 2) + 2L
32 = 2L - 4 + 2L
32 = 4L - 4
36 = 4L
9 = L

so our length is 9 meters.

w = L - 2
w = 9 - 2
w = 7

so our width is 7 meters.
