Suppose you want to use a compass needle to measure the magnitude of a particular magnetic field. You plan to orient the field so it is perpendicular to the Earth's magnetic field. You have made a slight mistake, however, and instead the Earth's magnetic field makes an angle of 85° with respect to the field you want to measure. What is the percentage error in your observation?

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 .
