0 feet.

Step-by-step explanation:

h = -16t^2 + 12t + 4

h = -4(4t^2 - 3t - 1)

= -4(4t + 1)(t - 1)

After 1 second height = -4 * 1 * 0 = 0 feet.

It's saying that on every other stop(with even numbers)you add 2 people, and on all the other stops(odd numbers)you subtract 5 people. Be sure that you start with 18 people on the bus! Keep doing this until there is no more people on the bus!
