A compass contains a magnet. The magnet responds to Earth's magnetic field. The magnet's north pole points north from most locations on Earth. Based on what you learned about magnetic force, make three predictions, Predict the
approximate size of Earth's magnetic field and the approximate location of its North and South Poles. Give a reason for
each prediction.

if you answer my question i will answer yours

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 .
