Two ship fog horns have different frequencies. They are both being blown at the same time. You hear a sound that varies in amplitude, with the time between a minimum in loudness and the next maximum in loudness being 0.14 seconds. You know the fog horn with the lower pitch has a frequency of 173.5 Hz. What is the frequency of the fog horn with a higher pitch

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

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 .
