I believe this is correct, if not lmk!
The domain is the set of allowed inputs, in this case t values. The smallest t value allowed is t = 0. The largest is t = 165. So that's why the domain is

-------------------------------
The range is

since H = 0 is the smallest output of the function and H = 40,000 is the largest output. Like the domain, the range is the set of possible outputs of a function.
Input is 4
so y=-2(4)+11
y=-8+11
y=11-8
y=3
Ans
(4,3)
