    I need help with function models

    During a football ball is game, a football is thrown by a quarterback who is 2 m tall. the football travels through the air for 4 s before it is caught by the wide receiver.

    I was told to write an equation out of this, but there isn't enough information right?

    And it goes on asking to write an equation with these 2 features:
    - the ball reached a max. height of 22m
    - the wide receiver who caught the ball is also 2m tall.
    I forgot how to write the equation when maximum height is given...

    Your help is greatly appreciated!
    Thanks

    It appears to me that you could model this with a quadratic.

    Start by writing down your known coordinates, then I would suggest using the turning point form

    y= a(x - h)^2 + k where (h, k) is the turning point.
