Question

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.
Find the time it takes the soccer ball to reach its maximum height in seconds​

Answer 1

`\displaystyle √(3)\:sec.`

Step-by-step Step-by-step explanation:

`\displaystyle -54 = -18x^2 → (-54)/(-18) = (-18x^2)/(-18) \\ \\ 3 = x^2 → √(3) = x`
