Math/Application Review 6. The most massive train was put together in South Africa in 1989 and traveled 861 km. This
acceleration from rest to an average speed of 38 kr/hr was 0.191 m/s? What then would be
the size of the unbalanced force that the locomotives exerted on the cars of the train?

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

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 .
