1.	The domain of a relation is all positive integers less than 4. The range of y or the relation is 2 plus x, where x is a number of the domain. Write the relation as a table of values and as an equation.
		A.	None of these.	B.
		C.		D.
		Hint
	2.	State the domain and the range of the relation {(1, 2), (-4, 2), and (3, 5)}. Then state whether the relation is a function.
		A.	The domain is {-4, 1, 3}, the range is {2, 5}, and the relation is a function.	B.	The domain is {2, 5}, the range is {-4, 1, 3}, and the relation is a function.
		C.	The domain is {-4, 1, 3}, the range is {2, 5}, and the relation is not a function.	D.	The domain is {2, 5}, the range is {-4, 1, 3}, and the relation is not a function.
		Hint
	3.	If j(x) = x2 + 1, find j(a + 1).
		A.	a2 + 2a + 1	B.	a2 + a + 1
		C.	a2 + 2a + 2	D.	a2 + a + 2
		Hint
	4.	State the domain of the function
		A.	all real numbers except 0 and 3	B.	all real numbers except 3
		C.	all real numbers except 0	D.	all real numbers except 0, 1, and 3
		Hint
	5.	State the domain and range of the relation. Then state whether the relation is a function.{(2,-1), (-2,4), (2,5), (3,6)}
		A.	Domain {-2,2,3} Range {-1,4,5,6} The relation is a function.
		B.	Domain {-2,2,3} Range {-1,4,5,6}The relation is not a function.
		C.	Domain {-1,4,5,6}Range {-2,2,3} The relation is not a function.
		D.	Domain {-1,4,5,6}Range {-2,2,3}The relation is a function.
