Abowling ball traveling with constant speed hits the pins at the end of a bowling lane 16.5m long. the bowler hears the sound of the ball hitting the pins 2.50s after the ball is released from his hands. what is the speed of the ball? the speed of the sound is 340 m/s.

he made 11 calls in one day

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 .
