A food packet is dropped from a helicopter and is modeled by the function f (x) = - 16x2 + 14400. The graph below shows the height f (x), in feet, of the food packet at different times x, in seconds:

Use the graph to determine the reasonable domain of f (x) based on the context.

a.) 0 _ x _ 30

b.) 0 _ x _ 14400

c.) - 30 _ x _ 30

d.) All real numbers
