A pair of glasses is dropped off a bridge 640 feet above a river. The polynomial - 16t2 + 640 gives the height of the glasses t seconds after they were dropped. Find the height of the
glasses when t=6.

Identify the function that contains the data in the following table: x     -2         0         2         3         5     f(x)     5         3         1         2         4     possible answers: f(x) = |x| + 1 f(x) = |x - 2| f(x) = |x - 2| - 1 f(x) = |x - 2| + 1
