Determine whether the formula describes y as a function of x. Explain your reasoning. (2 points) y = -x

Yes, it describes y as a function of x.

Step-by-step explanation:

A function describes y as a function of x if we have:

y = f(x)

where f(x) can be any function.

in this particular case, we have:

y = -x

so we can get this like f(x) = -x, that as we know this is a function of x.

then the relation y = -x is a function of x.

Another way to see it is that this actually is written as:

y = -1*x

the variable that is not being affected is the one being described, (in this case y) and the other variable is the variable of the function (in this case x.)
