Two cars collide with each other, before the collision one car ( m=1000 kg) is going north at 20m/s and the other car (m=1200 kg) s going south at 25 m/s. what is the momentum of the system made up of the two cars after the collision

the answer for apex users is 10,000 kg m/s SOUTH

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 .
