orbit

Explanation:

Our sky is divided into 88 areas known as constellations. These constellations are identified by the brightest stars of these areas forming a recognizable pattern. As the Earth travels in its orbit around the Sun, different constellations are visible at different times of the year. This is because different part of the sky is visible as earth goes around the Sun.

Thus, As Earth travels in its orbit different constellations are visible at different times of the year.

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 .
