The domain of the function is w > 0
The function is given as:
H(w) = 75/w
For the function to have a real value, the value of w cannot be 0
i.e.
[tex]w \ne 0[/tex]
Also, the value of w cannot be negative because width cannot be negative
This means that the possible values of w are greater than 0
Hence, the domain of the function is w > 0
