A soccer ball was kicked in the air and follows the path h(x)=−2x2+1x+6, where x is the time in seconds and h is the height of the soccer ball. At what time will the soccer ball hit the ground?

Step-by-step explanation:

The soccer ball was kicked in the air and follows the path as :

Here, x is the time in seconds and h is the height of the soccer ball.

We need to find the time at which the soccer ball hit the ground. It means that its height at a function of time becomes 0. So,

h(x) = 0

The above equation is a quadratic equation. It can be calculated as :

So, at 2 seconds the ball will hit the ground.

answer is b.
