1.	Determine whether the function f(x) = is continuous at x = 1.
		A.	No, because substituting x = 1 results in a denominator of 0.	B.	Yes, the inability to divide by 0 has no bearing on this problem.
		C.	Yes, it is continuous at x = 1, but not at x = -1.	D.	None is correct.
		Hint
	2.	Describe the end behavior of f(x) = x2 + 1.
		A.	As x , f(x) , and as x , f(x) .
		B.	As x , f(x) , and as x , f(x) .
		C.	none of these
		D.	As x ,f(x) , and as x , f(x) .
		Hint
	3.	Describe the end behavior of the function: f(x) = x4 - x3 + x2 + x - 1
		A.	f(x) as x , f(x) as x
		B.	f(x) as x , f(x) as x
		C.	f(x) as x , f(x) as x
		D.	f(x) as x , f(x) as x
		Hint
	4.	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 x < 0 and x > 0
		B.	increasing for all x
		C.	increasing for x < 0 and decreasing for x > 0
		D.	decreasing for all x
		Hint
	5.	Determine the intervals on which the function f(x) = is increasing and the intervals on which the function is decreasing.
		A.	increasing for x < -1 and decreasing for x > -1
		B.	increasing for x < -1 and x > -1
		C.	increasing for all x
		D.	decreasing for x < -1 and increasing for x > -1
