How to add two functions reciprocal functions and find the domain

The video tutorial covers the addition of functions using different notations, emphasizing the importance of common denominators when combining functions. It explains how to find common denominators for binomial expressions and simplifies expressions using these denominators. The tutorial concludes with determining the domain of a function, highlighting the need to factor denominators to avoid zero values.

What is the equivalent expression for F + g of X?

• F(X) + g(X)

• F(X) - g(X)

• F(X) / g(X)

• F(X) * g(X)

Why is it important to find a common denominator when combining functions?

• To simplify the numerator

• To ensure the functions are multiplied correctly

• To add the functions accurately

• To divide the functions properly

What is a common method to find a common denominator for binomial expressions?

• Subtract the denominators

• Multiply the denominators

• Add the denominators

• Divide the denominators

Why is it beneficial to keep the denominator factored when finding the domain?

• It makes the function easier to graph

• It simplifies the numerator

• It helps identify values that make the denominator zero

• It reduces the function to its simplest form

What values are excluded from the domain of the function discussed?

• X cannot equal 0 and 2

• X cannot equal -1 and 1

• X cannot equal 1 and 3

• X cannot equal 2 and 4
