The height of a soccer ball that is kicked from the ground can be approximated by the function:
y = -18x^2 + 54

where y is the height of the soccer ball in feet x seconds after it is kicked.

Answer:

[tex]\displaystyle \sqrt{3}\:sec.[/tex]

Step-by-step explanation:

[tex]\displaystyle -54 = -18x^2 → \frac{-54}{-18} = \frac{-18x^2}{-18} \\ \\ 3 = x^2 → \sqrt{3} = x[/tex]
