Question

What is the domain and range of `d(s)= 0.04s^2`?

Answer 1

Assuming we are restricted to Real numbers (`RR`)
the domain is all of `RR` and
the range is all of `RR` which is `>= 0`

Explanation:

`d(s) = 0.04s^2`
`color(white)("XXXX")`is valid for all Real values of `x`

Since (for all Real values of `x`) `x^2` is `>= 0`
`color(white)("XXXX")`the range of `d(s)` is all Real values `>=0`
`color(white)("XXXX")` `color(white)("XXXX")`(Note that the constant multiplier `0.04` is irrelevant to determining the domain or range)
