The SI system of units is better than the MKS system, New Creative Science, Class 9​

Yes true SI unit is better as it applies same over international level ..

Yes, the SI system of measurement is better than the MKS system of measurement.The system is widely accepted. It makes measurement more scientific, convenient and easy so it is better than MKS system.

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 .
