◉Limits as x approaches +- infinity. Answer: When you are taking
limits as x approaches +- infinity, you want to look at the highest
power on top and bottom
◉CASE 1: The powers are the same. Answer: Rule: divide
coefficients
◉CASE 2: The power on bottom is bigger. Answer: Rule: ZERO
◉CASE 3: The power on top is bigger. Answer: Rule: DNE ( +-
infinity)
◉Continuity. Answer: A function is continuous at a point, a, if it
satisfies the following:
1. f(a) exists
2. lim x>a f(a) exists
3. the limit = f(a)
