Mrs. Schepp drops a rubber ball from a height of 123 m. How long does it take to hit the ground?

force tends to be low and long diustance masses are high

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 .

because if the tool that you are using is not balanced it there would be false mass.
