Radio waves of frequency 600 khz are received at a location 10.0 km from the transmitter. the radio reception temporarily fades due to destructive interference between the direct beam and that reflected from a horizontal layer of charged particles formed in the atmosphere by a passing aircraft. calculate the minimum height of the aircraft?

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.

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 .
