Looking at the function h(t), it is a polynomial function.
The domain of this type of function usually is all real numbers.
But in this case, since the independent variable t represents the time, its value can't be negative, it usually starts at t = 0.
Therefore the appropriate domain for this situation is all non-negative numbers:
The correct answer is 12
Set up a ratio and then solve. See paper attached. (:
