**TL;DR Summary:**I want to mainly figure out where in the problem solving I went wrong. I understand the correct answer (since I looked it up), but to me, it does not make any sense.

I am honestly stumped at this point. Online solutions say that my equation y = 0.5774x-0.003354x^2 should instead be -y = 0.5774x-0.003354x^2 since "the change in y is negative"...

However, would the value y just be solved to be a negative value if all calculations are done correctly? I used a graphing calculator to check as well and the function, y = 0.5774x-0.003354x^2 is extremely different from how I imagine the projectile motion of this ball to look. Did I make a mistake somewhere while eliminating the parameter t from the equations? Or was there an assumption I made in solving that cannot be made? Thank you for the help in advance :).
