Sure! Here's a sample problem for a pre-calculus student:

Yu're standing on the ground and throw a baseball, whose trajectory follows the function:


$$
f(x) = -(x+2)^2 +4
$$

Where $x$ is the distance in meters from where you're standing, and $f(x)$ is the height the baseball troughout it's trajectory.

How far does the baseball reach from where you where standing?

Furthermore, what's the higuest point the baseball reached?
