12. Two objects collide and experience an inelastic collision. One is 19kg and moving east at 22m/s. The other is 6kg and moving south 10m/s. Determine the resulting velocity after
impact

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator

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 .
