Which relation is a function?

Mathematics

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 15 ft. shorter than its length. Its perimeter is 262 ft. Let l equal the length of the rectangle.
masha68 [24]
Let the length be l.
For now, let's make the width be w. 
Additionally, l = w + 15. Using this equation, width can also be written as l - 15. 
The perimeter of a rectangle is length + length + width + width. This can also be written as l + l + (l-15) + (l-15) = l + l + l - 15 + l - 15 = 4l - 30.
Using this equation:
4l - 30 = 262
4l = 292
l = 73

4(w + 15) - 30 = 262
4w + 60 - 30 = 262
4w + 30 = 262
4w = 232
w = 58

A rectangular prism has a base that is 5 cm by 7 cm and a height of 12 cm. if all dimensions are doubled, what happens to the vo
Maurinko [17]
We know, Volume of rectangular prism = l * b * h
If all dimensions are doubled, then it would be: 2 * 2 * 2 * v
V' = 8V

In Short, Volume will increase to it's 8 times
