Answer:
D.
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We see that our x-values span from -1 to 4. Since -1 is an open dot, it is not included in our domain:
(-1, 4] or -1 < x ≤ 4
The restriction are that neither h nor g may equal zero as that would lead to division by zero.
The simplification after units cancel is:
(3(gh)^3)/100 or if you prefer
0.03(gh)^3
