Answer 2

@Frwakygamereyes a relation defined from x \(\longrightarrow\)y is not a function when for one value of x there are several values of y.

Answer 3

I mean more than one

Answer 4

See this
\[x \longrightarrow y\ R: \underline{(1, 2)}, (2, 3), (4, 5), \underline{(1,6)}\]
here you can see that for x=1 there are 2 values of y, so this is not a function
