Which best describes the current atomic theory? (2 points) Since it is only a theory it should not be used in practice.
O It has not been tested enough to be useful for developing technology.
O It is the most powerful explanation scientists have to offer at this time,
O There is very little chance it will be changed in the future.

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 .

electric field is a function of 1/r^2
