Why is fresh water a limited resource

As population and industries grow, the demand for water becomes too high, which results in water scarcity. The cycle between water use and waste treatment shortens the more water we use. The faster we use water, the faster we must recycle it.

Explanation:

anation:

frankly yes, because when you want inverse a function you must inverse it with line x=y

so when you inverse a function Df and Rf will convert together!
