Which statement below correctly describes earth's gravity?

a. the pull of earth's gravity depends only on the mass of the object.
b. the pull of earth's gravity on an object is not affected by the object's distance from earth.
c. as objects get farther from earth, the pull of earth's gravity increases.
d. as objects get closer to earth, the pull of earth's gravity increases.

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 .
