Rills, gullies, streams, rivers and tributaries are all caused by

Explanation:All these bodies of water are formed when water flows from the top, such as from a hill, mountain, or down a valley, etc. In these high areas, melting snow causes tiny streams of water to flow down. They are also formed when small bodies of water combine to form larger bodies. For instance, A stream is a channel along which water is continually flowing down a slope. Unlike gullies, streams rarely dry up. Small streams are also called creeks or brooks. As streams flow together, they form larger and larger bodies of flowing water. A large stream is often called a river

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
