Un arquero lanza una flecha horizontalmente con una velocidad de 30 m/s. Considerando que el indio se encuentra sobre una torre y que
transcurren 3s desde que la Flecha sale del arco hasta que se clava en el suelo plano ubicado en la base de la Torre, determine:
a) La altura aproximada de la Torre (altura de disparo)
b) El alcance máximo (distancia horizontal medida desde la posición
de disparo hasta la posición final de la flecha)

Ayúdenme porfi):

the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

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 .
