A quarterback can throw a receiver a high lazy lob pass or a low quick bullet pass. these passes are indicated by curves 1 and 2 respectively in figure 4-23. (a) The lob pass is thrown with an initial speednofn21.5m/s and it's time of flight is 3.97s. what is its lunch angle. (b) the bullet pass is thrown with a launch angle of 25.0 degree. what is the speed of thisnpass? (c) what is the time of flight of the bullet pass

that would be because of both gravity and friction. so     c

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 .
