Each of the four corners of a square with edge 3.0 m is occupied by a point mass 12 kg. There is a fifth mass, also 12 kg, at the center of the square. To remove the mass from the center to a point far away, how much work that must be done by an external agent

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 .
