1.	Determine whether the function f(x) = 2x2 - x + 2 is continuous at x = 2.
		A.	Yes, because the function is defined at x = 2 and approaches y = 8 on the left and right sides of x = 2.	B.	None of these are correct.
		C.	Yes, because the function approaches the same y-value 8 on the left and right sides of x = 2.	D.	Yes, because the function is defined at x = 2.
		Hint
	2.	Determine whether the function f(x) = is continuous at x = 1.
		A.	None is correct.	B.	No, because substituting x = 1 results in a denominator of 0.
		C.	Yes, it is continuous at x = 1, but not at x = -1.	D.	Yes, the inability to divide by 0 has no bearing on this problem.
		Hint
	3.	When is the function f(x) = continuous at x = 2?
		A.	not enough information is given	B.	sometimes
		C.	always	D.	never
		Hint
	4.	Describe the end behavior of f(x) = x2 + 1.
		A.	none of these
		B.	As x , f(x) , and as x , f(x) .
		C.	As x ,f(x) , and as x , f(x) .
		D.	As x , f(x) , and as x , f(x) .
		Hint
	5.	Determine the intervals on which the function f(x) = x3 + x2 + x is increasing and the intervals on which the function is decreasing.
		A.	increasing for all x
		B.	increasing for x < 0 and x > 0
		C.	decreasing for all x
		D.	increasing for x < 0 and decreasing for x > 0
