Answer:

Domain: #x in {-1, -5, -4, 10, 5}#
Range: #y in {-9, -10, 1, -6, -2}#

Explanation:

Assuming the given set represents values of #(x,y)# where #x# is being mapped into #y# (that is #y# is a function of #x#).

If #y# is a function of #x#

#color(white)("XXXX")#The domain is the set of all valid values for #x#.

#color(white)("XXXX")#The range is the set of all valid values for #y#
