Polynomial Functions with real world problem

Jose Altuve hit a baseball. The path of the ball was modeled by this equation: $h\left(t\right)=-16t^2+96t+3$  where  $h\left(t\right)$ is the height of the ball in feet and  $t$  is the number of seconds the ball was in the air.

What was the maximum height that the ball reached?

• 96 feet

• 147 feet
  

• 16 feet

• 3 feet
