A neutron star's immense gravitational attraction is due primarily to its small radius and A neutron star's immense gravitational attraction is due primarily to its small radius and rapid rotation rate. large mass. strong magnetic field. high temperature.

Large mass.

Explanation:

A neutron star is one whose whole mass is concentrated in a small space. Thus, a neutron star has a very large mass and and a small radius. We know that Gravitational force

That is F is directly proportional to mass and inversely proportional square of radius. Therefore,  a neutron star has an  immense gravitational attraction

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 .
