illustrate the limit laws apply the limit laws in evaluating the limit of algebraic functions (polynomial, rational & radical). Learning Outcomes
What are laws and why are they created? Introduction
For sure there will be lots of explanation about it, one of which is that, it is a rule that is meant to be followed for greater good. Introduction
LIMIT LAWS The limit of a constant is itself. If k is any constant, then, ย 1. CONSTANT LAW
LIMIT LAWS The limit of ๐ฅ as ๐ฅ approaches ๐ is equal to c. That is, ย 2 . LIMIT OF โXโ LAW
LIMIT LAWS The limit of a constant ๐ times a function is equal to the product of that constant and its functionโs limit. ย 3. CONSTANT MULTIPLE THEOREM
LIMIT LAWS The limit of a sum of functions is the sum of the limits of the individual functions. ย 4 . ADDITION THEOREM
LIMIT LAWS The limit of a difference of functions is the difference of the limits of the individual functions. ย 5. SUBTRACTION THEOREM
LIMIT LAWS The limit of a product of functions is the product of the limits of the individual functions. ย 6 . MULTIPLICATION THEOREM
LIMIT LAWS The limit of a quotient of functions is the quotient of the limits of the individual functions. ย 7. DIVISION THEOREM
LIMIT LAWS The limit of an integer power ๐ of a function is just that power of the limit of the function. ย 8. POWER THEOREM
LIMIT LAWS If ๐ is a positive integer, the limit of the ๐๐กโ root of a function is just the ๐๐กโ root of the limit of the function, provided that the ๐๐กโ root of the limit is a real number. ย 9 . RADICAL/ROOT THEOREM

Wrap-up Vic and Joey argue about the limit of the function ๐(๐ฅ) = as ๐ฅ approaches 0. Vicโs opinion is that the limit is 0 while Joey claims that the limit does not exist. Write a short explanation that discusses the pros and cons of Vic and Joeyโs opinion. ย
