Question 96452: Determine the domain and range of each relation:

I really don't understand this ?

You can put this solution on YOUR website! Determine the domain and range of each relation:
y=2x-3
---------
Domain means the set of values that the "x" can accept.
In your problem the answer is "all Real Numbers" since
there is nothing about the equation that would restrict
your choice of Real Number replacements for "x".
---------------
Range means the set of numbers generated by the equation,
symbolized by the varible "y". In your problem the answer
is "all Real Numbers" since there is no Real Number value
you could not substitute for y and find a corresponding
Real Number value for "x".
