Is this a function:
x + y = 12

a. yes
b. no
c. it depends
d. none of the above
A function is a well-behaved relation.
Based on this definition, then it is a function.
There is a relationship between x and y. Together they add up to 12.
We can also replace x with different numbers and then subtract those numbers from 12 to find different y values and vice-versa.
So, yes, it is a function.
