680 the Fan broadcast at AŃ 680 KHz, what is the wavelength? a. 441.18 m
C. 4.41 Hz
b. 441,176.47 Hz
d. 441,176.47 m

are there answer choices to this question? this seems like a question where you have options to choose from.

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 .
