A50 kg box is at rest on a horizontal surface. when an 80 n force is applied to the box, it slides on the surface with a constant velocity. how will the force of friction change if an identical box is placed on top of the 50 kg box

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 .
