Given:

To find:
The set of points that includes all of the solutions for the given equation.
Solution:
From the given equation, it is clear that y-values depend on the x-values.
If x is a real number, then y-values are real numbers such that
.
So, the set of points that includes all of the solutions for the given equation is defined as
for all real numbers.
Therefore, the correct option is B.
