Question

Determine whether the formula describes y as a function of x

Answer 1

y = -x is the function. I'm not sure exactly what they're asking

Answer 2

y being a function of x means that the changes in y rely on the changes in x. In simpler terms, x causes y. So yes, it is. Or at least that's how I see it.
