When an airplane communicates with a satellite using a frequency of 1.535 ×109 hz, the signal received by the satellite is shifted higher by 207 hz. (a) is the airplane moving toward or away from the satellite? explain. (b) what is the componentof the airplane’s velocity toward or away from the satellite?

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 .
