The height of the elevator would be modeled as H = -4t + 90.
The domain of the function is 0≤t≤6, while the range of the function is 66≤H ≤90
In a total of 6 months, the elevator would have to descend for about 4 meters. 6 x 4 = 24meters.
hence we would have 90 - 24 = 66m
Hence the elevator would descend at 66 meters.
This gotten from the formula H = -4t + 60 = 66m
