# Thread: I need help with function models

1. ## 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...

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