The height of a curved support beam can be modeled by
F(x)=- x^2/288 +18
Find the height and width of the beam.

Height = units
Width = units

I bet you mean F(x)=- x^2/288 +18 x

-288 y = x^2 - 5184 x
-288 y + 6718464 = x^2 - 5184 x + 6718464
-288 y + 6718464 = (x-2592)^2
vertex at x = 2592 and height = 23328
length = 2592*2 = 5184
