Answer:
No
Step-by-step explanation:
You can tell if something is a function by checking to see if a vertical line will intersect at one spot more than once. If it does, it is not a function.
Strictly speaking an equation does not have a domain. A function does. Though it may make sense to speak about a solution set to this equation over a domain.
The following could be helpful towards an answer: The equation has two sides. The left hand side is a non-linear function and the right hand side is a line with slope -1 and y-intercept of 1.
The function
has a domain over all Reals x for which it holds
so the domain of the nonlinear function is
.
The domain of the linear function 1-x is all Reals: 
So, together you could say the equation's solutions are defined over the domain
.
