No because it only needs to pass the y-axis once to be an function

# data[].attributes.body
No it is not a function, it should only pass through once.

# data[].attributes.body
No, it can only pass once through the y-axis.

# data[].attributes.body
No,because it has to pass the vertical line test

# data[].attributes.body
It is not a function  because it passes through 2 times it's only suppose to happen twice.

no because it has to pass the vertical line test

# data[].attributes.body
If it crosses pass the y-axis twice it doesn't pass the vertical line test.

A relation is not a function is it passes through the y-axis TWICE

# data[].attributes.subject
A relation is not a function is it passes through the y-axis TWICE

# data[].attributes.body
A relation is not a function if it passes through the y-axis twice because it should only pass one time through the y-axis for it to be a function.

# data[].attributes.body
No, because it can only pass through the y-axis once.

# data[].attributes.body
No its not a function because a function passes the vertical line test.

# data[].attributes.body
No it wouldn't be a function since it doesn't pass the vertical line test. Since it doesn't that means it isn't a function.

# data[].attributes.body
No, it is not a function because if you were to do a vertical line test then it would fail.

# data[].attributes.body
If it passes through the y-axis twice, it's function, but it won't be function if it passes through the x-axis twice.

# data[].attributes.body
No. It is not a function if it passes through the y-axis twice because it can only pass y-axis once.

# data[].attributes.headline
No, it is not a function because if you were to do a vertical line test it woulds fail.

# data[].attributes.body
No, it is not a function if it passes through the y-axis twice as if you were to use the vertical-line test it would fail because it passes through more than one line.

# data[].attributes.body
No it is not a function because a function is a relation where there is only one output for each input.

# data[].attributes.headline
No it is not a function because there can only be one x-value with one y-value. Plus it will fail the vertical line test.

# data[].attributes.subject
No it is not a function because there can only be one x-value with one y-value. Plus it will fail the vertical line test.
