Ionic bonding happens when one atom gives one or more electron and the other atom receive them. in covalent compounds a
at least two electrons have to be given
b
only one electron can be received
c
atoms share electrons instead of exchanging
d
non of the above is true

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 .

there are no contact forces mentioned on the list of choices that you've provided.
