The video tutorial explains how to verify if two functions are inverses by using function composition. It demonstrates the process of plugging one function into another and simplifying complex fractions by multiplying by the reciprocal. The tutorial also covers verifying that F(G(X)) and G(F(X)) both equal X, confirming the functions are inverses.

What is the main goal when verifying two functions using F of G of X?

• To ensure F of G of X equals X

• To ensure F of G of X equals G of F of X

• To ensure F of G of X equals F of X

• To ensure F of G of X equals G of X

When simplifying a complex fraction, what is the first step?

• Add the fractions together

• Subtract the smaller fraction from the larger one

• Divide the numerator by the denominator

• Multiply by the reciprocal

In the example given, what is the reciprocal of 7/X?

• 7/X

• 1/X

• X/1

• X/7

What happens to the sevens when simplifying 7/1 * X/7?

• They remain unchanged

• They divide to one

• They divide to zero

• They multiply to 49

What is the result when both F of G of X and G of F of X are verified?

• Both equal zero

• Both equal F of X

• Both equal G of X

• Both equal X
