Function Transformations and Inverses

The video covers a review of function transformations, including moving functions, stretching, and reflecting them. It explains function notation, mapping notation, and inverse functions. The lesson includes practice problems and solutions, preparing students for an upcoming quiz. The teacher emphasizes the importance of nested brackets in function notation and provides instructions for further practice and assignments.

What is the primary focus of function transformations?

• Changing the color of the graph

• Decreasing the function's complexity

• Altering the shape and position of the graph

• Increasing the number of variables

In function notation, what does the 'a' parameter affect?

• Horizontal shift

• Vertical stretch

• Horizontal stretch

• Vertical shift

Why are nested brackets important in function notation?

• They are used to add color to the graph

• They separate horizontal stretch from horizontal translation

• They make the equation look complex

• They simplify the function

What is the first step in solving a function transformation problem with nested brackets?

• Ensure the brackets are correctly placed

• Add more variables

• Ignore the brackets

• Change the function type

What does mapping notation help with in function transformations?

• Simplifying the function

• Changing the function type

• Moving a point from the original to the transformed location

• Adding more variables

How can you determine if an inverse function is also a function?

• By checking the vertical line test

• By checking the horizontal line test

• By simplifying the function

• By counting the number of variables

What is the first step in finding the equation of an inverse function?

• Change the function type

• Switch the x and y coordinates

• Add more variables

• Simplify the function

In a diploma exam question, what is a common strategy for solving transformation problems?

• Change the function type

• Ignore the function notation

• Use the vertex form to identify transformations

• Add more variables
