Understanding Inverse Functions

The video tutorial explains inverse functions, which are essentially the opposite of original functions. It covers how to identify inverse functions using a negative one notation, provides examples to illustrate the concept, and demonstrates how inverse functions can be visualized on graphs. The tutorial emphasizes the flipping of x and y values in inverse functions and concludes with a summary of key points.

What does the term 'inverse' imply in the context of functions?

• A function that is identical to the original

• A function that is divided by its variable

• A function that is flipped or opposite

• A function that is multiplied by two

In a table, if the original function gives an output of 60 for an input of 10, what would the inverse function do?

• Output 0 for an input of 60

• Output 20 for an input of 60

• Output 60 for an input of 10

• Output 10 for an input of 60
