A rock is thrown horizontally from a 150m tall cliff at 6.00m/s. How much time does it take to hit the ground below? and how far away from the base of the cliff does the rock hit the ground below?

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure

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 .
