Why did most countries change to the metric system? Help pls!!

Most British Commonwealth nations changed from the imperial system of units to the metric system. Several of these nations rapidly and successfully made the metric transition, thanks to strong government encouragement and support. In addition, other countries have also made the change.

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 .
