Question

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.

Answer 1

can you help @mathmath333 ?

Answer 2

wait

Answer 3

sure can do :D

Answer 4

so the domain are the x values , but we want domain such that
\(f(x)\geq 200\)

so see the graph such that \(y\geq 200\)

Answer 5

see and tell if that makes sense

Answer 6

??

Answer 7

hmm.... im not quite following :(

Answer 8

see the file and tell the x values

Answer 9

0 ≤ x ≤ 15

Answer 10

yes

Answer 11

that's the domian
