Question

What is the domain and range of `d(s)= 0.006s^2`?

Answer 1

Domain: `s in RR`
Range: `AAd>=0; d in RR`

Explanation:

`d(s)=0.006s^2` is valid for all values of `s in RR`

For `AAs in RR, s^2 >=0 rArr 0.006^2 >= 0`
furthermore, as `abs(s) rarr +oo, d(s) rarr +oo`
therefore the range of `d(s)` is `[0,+oo)`
