The cheerleaders at a football game launch T-shirts into the crowd from the back of a golf cart that is 2 feet off the ground. The T-shirts have an upward velocity of 30 feet per second. Using the function y=−16t2+30t+2%0D%0A%0D%0A=%0D%0A−%0D%0A16%0D%0A%0D%0A2%0D%0A+%0D%0A30%0D%0A%0D%0A+%0D%0A2%0D%0A, which of the following correctly identifies the y-intercept and best explains its meaning?
The y-intercept of the function y = -16t^2 + 30t + 2 is 2.
The y-intercept represents the initial height of the T-shirts when t = 0. In this case, when the golf cart is just starting to launch the T-shirts, they are already 2 feet off the ground.
