What is the domain of the given function? {x | x = –6, –1, 0, 3} {y | y = –7, –2, 1, 9} {x | x = –7, –6, –2, –1, 0, 1, 3, 9} {y | y = –7, –6, –2, –1, 0, 1, 3, 9}

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
