The school auditorium was being rebuilt. When the orchestra practiced during construction, the sound seemed to bounce all around the room. Before the concert, workers installed thick panels of light material with many holes. The sound was very different during the concert. Explain what happened to cause the change in sound.

c) up is the direction the magnetic force is acting on the charge.

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 .
