Domain: #x = 3#
Range: #y in {7, 8, -2, 4, 1}#

Explanation:

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

#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#

Note: This explicit set mapping is not a function (since the same value of #x# maps into multiple values of #y#)
