Explore the law of conservation of mass. model a physical or chemical change, and then demonstrate how mass is conserved before and after the change. the image shows how the total number of atoms before and after a chemical reaction equals one another two purple circles plus two red circles to make a new substance with two molecules each made up of one red circle attached to one purple circle

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 .
