Question
The arch support of a bridge can be modeled by y=-0.0012x^2 where x and y are measured in feet. Find the height and width of the arch.
I don't know how to even attempt to solve this... If you know how, can you PLEASE help asap!!

This cannot be right, as the vertex is at (0,0)
You need an equation of the form
y = a - bx^2
where the height of the arch is at a, and the width is 2√(a/b)
