Answer 1

What's confusing you?

Answer 2

the way it is phrased is confusing

Answer 3

You're given some formula, say, \(y=-x\), and you're asked to tell whether it describes \(y\) as a function of \(x\) or not. Is \(y\) a function of \(x\) here? Can I write \(y=f(x)=-x\)?

Answer 4

yes because y= and f(x)= is the same idea

Answer 5

That's correct.

Answer 6

thank you
