Understanding Inverse Functions

The video tutorial explains how to find the inverse of a function by interchanging input and output values. It covers the concept of inverse functions, graphical representation, and the algebraic process to find inverses. The tutorial concludes with an example, demonstrating the steps to solve for the inverse of a given function.

What is the primary concept behind finding the inverse of a function?

• Switching the input and output values

• Multiplying the function by -1

• Adding a constant to the function

• Dividing the function by its derivative

Why is it often easier to use 'y' instead of 'f(x)' when finding an inverse?

• Because 'y' is always positive

• Because 'f(x)' is not a valid mathematical term

• Because it simplifies the algebraic process

• Because 'y' is a simpler letter

What is the first step in finding the inverse of a function algebraically?

• Divide by the coefficient of x

• Add 1 to both sides

• Change 'f(x)' to 'y'

• Multiply both sides by 2

In the example provided, what is the inverse of the function f(x) = 3x - 1?

• f inverse(x) = x - 1 / 3

• f inverse(x) = 3x + 1

• f inverse(x) = x + 1 / 3

• f inverse(x) = 1 - x / 3

What operation is performed after interchanging x and y to solve for y?

• Add 1 to both sides

• Subtract 1 from both sides

• Divide both sides by 3

• Multiply both sides by 3
