What are the two primary methods for determining one-sided limits?
One-sided limits can be determined analytically, using algebraic properties and theorems, or graphically, by observing the function's behavior as it approaches a value from one side.

What are the two primary methods for determining one-sided limits?
One-sided limits can be determined analytically, using algebraic properties and theorems, or graphically, by observing the function's behavior as it approaches a value from one side.
What types of combined functions can be evaluated using the main limit theorems?
The main limit theorems can be used to find the limits of sums, differences, products, quotients, and composite functions.
How do you find the limit of a sum of two functions, f(x) + g(x), as x approaches c?
Using the limit theorem for sums, the limit of a sum of two functions is the sum of their individual limits, provided both limits exist.
What are limit theorems?
Limit theorems are a set of rules used to determine the limits of functions by breaking them down into simpler operations like sums, differences, products, and quotients.
What is the overall purpose of using algebraic limit theorems?
The purpose is to analytically determine the limits of complex functions by breaking them down into simpler, manageable parts whose limits can be found more easily.
What is the rule for finding the limit of a quotient of two functions?
The limit of a quotient of functions is the quotient of their individual limits, provided that the limit of the function in the denominator is not zero.
State the limit theorem for the product of two functions.
The limit of a product of two functions is the product of their individual limits.
Define a one-sided limit.
A one-sided limit describes the value a function approaches as the input (x-value) approaches a specific point from either the left side or the right side only.
How does one find the limit of a composite function using limit theorems?
The limit of a composite function can be found by taking the limit of the inner function first, and then applying the outer function to that result, provided the functions meet certain continuity conditions.
How would you analytically determine the limit of a difference between two functions?
You would use the limit theorem for differences, which states that the limit of the difference is the difference of the individual limits of the two functions.
