You are trying to dunk a basketball. You need to jump 2.5 feet in the air to dunk the ball. The height that your feet are above the ground is given by the function \displaystyle f\left(t\right)=-16t^{2}+12tf(t)=−16t2+12t.What is the maximum height your feet will be above the ground (put your answer in decimal form and round to the nearest hundredth)?
