Is the following mapping a function? Why or why not?

# data[].attributes.body
1 ------> 3
0 ------> 4
2 -------> -5
4 ------> -5
1 -------> 8

# data[].attributes.body

No because 1 input is going to 2 separate outputs

# data[].attributes.body
this is not a function because there is 1 inputs that has 2 different outputs.

# data[].attributes.body
not a function
