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)
