if the x value is reapeted in a set of x values, is it a function?
when finding a function do you loko at x values or y values?

Respuesta :

yes it is still a function it just wont be linear
❅☃ If the x value is repeated it is considered a non-function.
So if we had x values of:
2
3
6
it is a function
but if we had 
3
6
6
it is a non function because the 6 was repeated
❅☃ Yes, you have to look at the x values, if you do not look at the x values, then you cant determine the functions.
