Learning Graph Transformations: Reflections, Stretches, and Squishes!

Understanding function transformations in graphs is essential for mastering how different mathematical operations affect graph shapes and positions.

  • The transformations include vertical and horizontal shifts, reflections across axes, and stretching or compressing graphs
  • Each transformation follows specific rules that modify either x or y coordinates
  • Vertical transformations affect y-coordinates while horizontal transformations affect x-coordinates
  • Reflections can occur across both x and y axes, creating mirror images of the original function
  • Stretching and compression factors determine how the graph expands or contracts

I love this app so much, I also use it daily. I recommend Knowunity to everyone!!! I went from a D to an A with it :D

Philip, iOS User

The app is very simple and well designed. So far I have always found everything I was looking for :D

Lena, iOS user

I love this app ❤️ I actually use it every time I study.

Function Transformations and Their Effects

This comprehensive page details various effects of function reflections and stretches on graphs, providing a systematic breakdown of common transformations.

The transformations are organized into several categories:

Definition: Vertical shifts y=f(xy = f(x + a) move the graph up when a is positive and down when a is negative.

Definition: Horizontal shifts y=f(x+ay = f(x + a) move the graph left when a is positive and right when a is negative.

Highlight: Reflections can occur in two ways:

  • y = -fxx reflects the graph across the x-axis
  • y = fx-x reflects the graph across the y-axis

Example: When dealing with stretches and compressions:

  • For y = kfxx: k > 1 creates a vertical stretch, k < 1 creates a vertical compression
  • For y = fkxkx: k > 1 creates a horizontal compression, k < 1 creates a horizontal stretch

Vocabulary:

  • Stretch: Expansion of the graph along an axis
  • Compression: Contraction of the graph along an axis
  • Reflection: Mirror image of the graph across an axis

This graph function compression and stretching explained guide serves as a fundamental resource for understanding how mathematical operations transform basic functions into more complex forms.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Best app on earth! no words because it’s too good

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

This apps acc the goat. I find revision so boring but this app makes it so easy to organize it all and then you can ask the freeeee ai to test yourself so good and you can easily upload your own stuff. highly recommend as someone taking mocks now
