William would like this bar magnet to move back and forth from left to right using attraction. what objects does he need to place at each end to make it move? • Place the South Pole of another magnet next to the South pole, and the North Pole of another magnet next to the north pole.

• Place the North Pole of another magnet next to the South pole, and the South Pole of another magnet next to the north pole.

• Place the South Pole of another magnet next to the South pole, and the North Pole of another magnet next to the South pole.

• Place the North Pole of another magnet next to the South Pole and the North Pole of another magnet next to the north pole.

I don't have an exact answer but this is what i know. sorry man.

Explanation:

If you line up two magnets so that the south pole of one faces the north pole of the other, the magnets will pull toward each other. This is called attraction. If you line the magnets up so that two of the same poles face each other, the magnets will push away.

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 .
