Question
D(3) = 30t + 15, find the domain and range

Answer
The domain is your horizontal or independent variable values it can take on. Here that variable is t. Linear equations are defined everywhere so t can be any real number that is the domain. By the way are you sure that it is D(3) and not D(t)? Assuming it is D(t) then for any value of t would D(t) not exist? In other words what vertical value would not occur for some value of t? I don't see where there is any D(t) that can't be found with the appropriate t so the range is all real numbers also.
