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.)

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
