Domain: x in RR
Range: f(x) in RR

Explanation:

After factoring, this equation becomes f(x) = 1/2x - 1.
In this equation there are no values that can result in f(x) becoming undefined (like 5/0). So, the domain of x Includes all real numbers.
The graph of f(x) is linear. It's a completely straight line so the range of f(x) would also include all real numbers.
