A food 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

when something falls, does it stop at the ground or go under the ground?

  • anonymous
It stops at the ground
Loser66
  • Loser66
Yes, so, although the graph passes the x axis, in fact, when it hits the ground, the function stop working, right?
anonymous
  • anonymous
right
Loser66
  • Loser66
hence, from the right, it stops here. |dw:1437400344228:dw|

-40
Loser66
  • Loser66
nope, the graph starts at -40, but the food package start falling at 0

Ohh okay

Hence from the left it is \(0\leq x\)
