Answer 1

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:

graph of function f of x equals 14400 minus 16 multiplied by x squared

Use the graph to determine the reasonable domain of f(x) based on the context.
0 ≤ x ≤ 30
0 ≤ x ≤ 14400
-30 ≤ x ≤ 30
All real numbers

Answer 2

all real numbers

Answer 3

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:

graph of function f of x equals 14400 minus 16 multiplied by x squared
..........f(x) = -16x² + 14400

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

Answer 4

You sure about that?

Answer 5

yeah why

Answer 6

It says "based on the context"

And the context says it is "dropped," meaning it started from a high point.

If we use "all real numbers that could mean that it could start from anywhere that is not the high point, meaning it won't be dropped, but arched.
