1.	Determine whether the function f(x) = 2x2 - x + 2 is continuous at x = 2.
		A.	None of these are correct.	B.	Yes, because the function is defined at x = 2 and approaches y = 8 on the left and right sides of x = 2.
		C.	Yes, because the function is defined at x = 2.	D.	Yes, because the function approaches the same y-value 8 on the left and right sides of x = 2.
		Hint
	2.	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
	3.	Describe the end behavior of this function:
		A.	y 3 as x , y 3 as x
		B.	y as x , y as x
		C.	y -2 as x , y -2 as x
		D.	y 0 as x , y 0 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.	decreasing for all x
		B.	increasing for x < 0 and decreasing for x > 0
		C.	increasing for all x
		D.	increasing for x < 0 and x > 0
		Hint
	5.	Determine the intervals on which the function f(x) = is increasing and the intervals on which the function is decreasing.
		A.	decreasing for x < -1 and increasing for x > -1
		B.	increasing for x < -1 and x > -1
		C.	increasing for all x
		D.	increasing for x < -1 and decreasing for x > -1
