Lexy and jin study the diagram shown
which best explains who is correct?
n = 2
n
=
1
lexy is correct because angle r is between the incident
wave, n = 0, and a diffracted wave.
lexy is correct because angle rincludes the diffracted
wave at n =
jin is correct because angle s is measured from the
barrier and includes n = 2, the wave that has the most
diffraction
jin is correct because angle s is between the dimmest
order bands, n = 1 and n = 2.
lexy says that the diffraction angle is the one labeled r
and jin says that the diffraction angle is the one labeled s

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 .
