Full solution stays hidden until you ask for it.
1. Write f(x)/g(x) in the requested order.
2. Apply domain restrictions from each function and from g(x)!=0.
3. Simplify if useful.
4. Interpret the quotient as a rate, average, or ratio.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
