Answer:

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.
