Based on the situation above, describe any necessary restrictions to the domain and range. Provide justification for the restrictions.

@Js555 There are no restrictions to the domain or range because it is a line. It's domain and its range are both real numbers. You can verify this at http://www.wolframalpha.com/input/?i=f%28x%29%3D-4x%2B102
