What is the domain and range of x=7?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The question is formulated unprofessionally.

The terms "the domain" and "the range" relate to functions.

These terms do not relate to equations.

What is written in the post is not a function.

It is an equality. (It even is not an equation.)

The correct answer to this post is

"It doesn't make sense."
