The rate of change is 3,000 ft./sec., and the initial value is 250 ft.
The rate of change is 3,000 ft./sec., and the initial value is 250 ft.

The rate of change is 250 ft./sec., and the initial value is 3,000 ft.
The rate of change is 250 ft./sec., and the initial value is 3,000 ft.

The rate of change is −250
ft./sec., and the initial value is 3,000 ft.
The rate of change is negative 250 ft./sec., and the initial value is 3,000 ft.

The rate of change is 3,000 ft./sec., and the initial value is −250
ft.

Answer 1

The correct response is:

The rate of change is −250 ft./sec., and the initial value is 3,000 ft.

This is because the falcon is descending, which means its elevation is decreasing at a rate of 250 ft./sec, hence the negative sign for rate of change. The initial value refers to the starting height, which is 3,000 feet.
