The domain of the given function H(w) is:
D: w > 0.
The domain of a function is the set of possible inputs that we can use in the function.
Here the function is:
H(w) = 80/w
Where w is the width of a rectangle, so it only can be a positive number.
Then we must have w > 0.
That is the only restriction we have on the input, then the domain is just:
D: w > 0.
