Question

Determine whether y= -x describes y as a function of x

Answer 1

Yes, because here y is the independent variable and x is the dependent variable.

Answer 2

Function: Correspondence (mapping) between two sets (domain and range) such that for every element in the domain, there is exactly one corresponding element in the range.

For it to be a function, for every x, there needs to be exactly one y. Do you have that?

Answer 3

yes

Answer 4

Then I suppose you have a function. Nice job. Do math every day.

Answer 5

thanks

Answer 6
