We have been given a quadratic function  and we need to restrict the domain such that it becomes a one to one 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 ![(-\infty,5]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C5%5D) or
 or  , it will become one to one function.
, 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
 if we restrict the domain of original function to  and the inverse function would be
 and the inverse function would be  if we restrict the domain to
 if we restrict the domain to ![(-\infty,5]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C5%5D) .

Answer is C. Definitely not d right off the bat because both exponents are negative so cross that out. After that its just counting zeros.
