Question

I did a lab based Projectile Motion and they ask me this question

Following the definitions of direct and inverse proportionality earlier, discuss why this equation shows that your answers for initial velocity and gravity are correct.

* Note that this range equation only works if y0 = yf

I think is because of the no air resistance but im not sure can you help me this one I don't want to know if I'm right or wrong?
