Afood packet is dropped from a helicopter and is modeled by the function f(x) = -12x2 + 19200. 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.
all real numbers
x ≤ 19200
-40 ≤ x ≤ 40
0 ≤ x ≤ 40
