Suppose a cannonball is launched off the top of a 44.1m cliff horizontally as shown in the picture. the cannonball gives out a reading telling you that the was launched in the horizontally direction with a velocity of 15m/s. you also time how long the ball is in the air and it is in the air for exactly 3 seconds. how far from the cliff does the ball land?

f is prop to m1xm2 double m1 double force

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 .
