How can I shorten this and for it to sill make sense? radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium

Radiation is the emission or transmission of energy in the form of waves.

Explanation:

.

Radiation is the transmission of energy. Radiation is formed in waves that can travel through space and through material.  

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 .
