A roller-coaster car has a potential energy of 700 kJ and a kinetic energy of 160 kJ at point A in its travel. At the low point of the ride,
the potential energy is zero, and 60 kJ of work has been done against friction since it left point A. What is the kinetic energy of the
roller coaster at this low point?

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 .

we need to see it
