A ,2 ton truck is traveling east through an intersection at 2m/s when it is hit simultaneously from the side and the rear. one car is a 1 ton compact traveling North at 5m/s .the other car is 1.5 ton midsize traveling east at 10 m/s . Three vehicles become entangled and slide as one body . What is their speed and direction after collision.

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 .

the awnser is d you right bro
