Answer:

Domain: #RR#
Range: #RR#

Explanation:

#y-4=1(x-4)# is equivalent to #y=x#

This equation is defined for all Real values of #x#, so the Domain is all Real values: #RR#.

The Range (the values possible for the dependent variable #y#) is equal to the Domain, so the Range is all Real values: #RR#.

(Actually, the Domain and Range could be considered to be the much larger collection of all Complex values: #CC#).
