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.		B.
		C.		D.	None of these.
		Hint
	2.	State the domain and range of the relation.
		A.	All real numbers are included in the domain, and 3 is included in the range.	B.	All real numbers are included in the domain and the range.
		C.	3 is included in the domain, and all real numbers are included in the range.	D.	3 is included in the domain, and 3 is included in the range.
		Hint
	3.	If j(x) = x2 + 1, find j(a + 1).
		A.	a2 + a + 1	B.	a2 + a + 2
		C.	a2 + 2a + 1	D.	a2 + 2a + 2
		Hint
	4.	State the domain of the function
		A.	all real numbers except 0	B.	all real numbers except 3
		C.	all real numbers except 0, 1, and 3	D.	all real numbers except 0 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 {-1,4,5,6}Range {-2,2,3}The relation is a function.
		C.	Domain {-2,2,3} Range {-1,4,5,6}The relation is not a function.
		D.	Domain {-1,4,5,6}Range {-2,2,3} The relation is not a function.
