The equation you provided is:

$y = -1 + 1 + 100$

This simplifies to:

$y = 100$

It appears that the equation doesn’t model the ball's parabolic trajectory properly. A typical equation for a ball's path is quadratic, like:

$y = -ax^2 + bx + c$

where $y$ is the height, $x$ is the horizontal distance, and the constants $a$, $b$, and $c$ describe the motion.

If you meant to provide such a quadratic equation and simply made a typo, please clarify it. However, if the equation truly simplifies to just $y = 100$, it means the ball remains at a constant height of 100 feet without rising or falling.

Let me know if you intended a different form of the equation!
