Given that your rocket was launched at 25 degrees and traveled 16 m down the hall, what was its launch velocity? once you find that launch velocity, assuming that your rocket always launches that fast, what is the ideal angle at which to launch it so that you maximize the distance it flies down the hall.
the ceiling is 2.74m tall

come closer and become far apart and become steam/gas

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 .
