Question

Does the following table represent a function?

Answer 1

x | y
------
2 | 1
3 | 1
4 | -3
5 | -3

Answer 2

I don't think so, but I wanted to double check.

Answer 3

This relation is a function.
It wouldn't be a function if there were 2 or more y-values to one x-value.

Answer 4

What does that mean?

Answer 5

I read that wrong, I had to read it three times over. #Dyslexia

Answer 6

So, you see, like in the question you posted. Two points will be at (2,1) and (3,1). This is ok, it'll still be a function.

But, a relation isn't a function if there are two or more y-values to an x-value.
So, like, a function can't have a points at (1,2) and (1,3) in it.

Answer 7

Because a function cant intercept cross Y more than once, right?

Answer 8

Right.
