Question

The set of ordered pairs a where

t is the time in seconds after
someone jumps out of a plane at
4000 meters to go skydiving, and d
is the displacement above the
ground

I need to find the domain and Range.

Answer 1

Answer: Domain is
`[0,\infty)` and range is [0,4000].

Explanation:

It is given that, the set of ordered pairs (t,d), where

t = the time in seconds after someone jumps out of a plane at 4000 meters to go skydiving

d = is the displacement above the ground.

It means t is independent variable and it is represented on the x-axis.

d is dependent variable and it is represented on the y-axis.

We need to find the domain and Range.

Domain is the set of input values.

Here, input is time and time can not be negative.

Domain
`=0\leq t=[0,\infty)`

Range is the set of output values.

Here, output is displacement above the ground which can not be negative or more than 4000 meters.

Range
`=0\leq d\leq 4000=[0,4000]`

Therefore, domain is
`[0,\infty)` and range is [0,4000].
