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)
