How many poles do you expect to see in your magnet? Look around your room. Make a list of 5 items that might be attracted to the magnet: Make a list of 5 items that you think will not interact with the magnet: Check your hypothesis in (1.2) and (1.3) using a magnet. Did the magnet attract all of the items on your list in (1.2)? Did it interact with any of the items in part (1.3)?

1.1 Two poles: North and South Poles.

1.2 - Staple pin - Nail - Tip of my phone charger - Metal keys - Cloth Hanger

1.3 - Wooden bed cot - Plastic pen - Game pad - Wooden shelf - Paper - A T-shirt

1.4 Yes

1.5 No

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 .
