If your'e looking to complete the square, then here's how you do it:
1.) Subtract 7 from each side:
2.) Take half of the value of B, which is 4, then square it to get C
3.) Now you should have
, because what you do to one side you have to do to the other
4.) Take the value of
and 4, and plug them into an ordered pair: 
Now take the square root of both sides which is equal to
±
5.) Now subtract 4 from each side to isolate x:

The range of a function is the set of all values that it can take when its independent variable takes values on the domain.
On the other hand, the range of a function is the domain of its inverse function, if that inverse exists, and vice-versa: the domain of a function is the range of its inverse function, if that inverse exists.
In the case of the given equation:
The inverse function exists since the function is linear, and it can be found by isolating <em>x</em>:
If the range of the original function is the set given by the number {
