Answer 2

Which one do you think?

Answer 3

hint:
a function \(y=f(x)\), is a relation between two variables, namely \(x,y\), such that for each vaòue of \(x\), we have one and \(only\) one value of \(y\)

Answer 4

oops.. value*

Answer 5

To find an answer you would see if there is a pattern between \(\large{x}\) and \(\large{y}\) one example is c...

We have \(\large{1}\) and \(\large{x}\) and \(\large{1}\) as \(\large{y}\) so how would you get from 1 to 1 well you would add zero....so continue this to see if it is in fact a function well \(\large{2+0=2~not~1}\) so C is in fact not a function...

Answer 6

We have 1 as x*

Answer 7

if you see x repeats it is not a function

Answer 8

The answer is the 2nd one... because the domain is not repeated.
