Carlos attempts to get a refrigerator magnet to stick on the s end of a bar magnet. he is unable to do so and states that the bar magnet is broken. evaluate his argument: is this correct or incorrect? explain.

It is incorrect.

Explanation:

Refrigerator magnets are actually multiple layers of magnets, and they are stacked using opposite polarities, so the south end of the magnet might be under a north, so if he puts the magnet on its side it will probably attract.

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 .
