Exponential Functions & Compound Interest Study Guide for Kids!

This study guide covers key concepts related to exponential functions and compound interest. It explains growth and decay patterns, formulas, and real-world applications.

  • Exponential functions are based on multiplication patterns, not addition
  • Growth occurs when the multiplier is greater than 1 (b > 1)
  • Decay happens when the multiplier is between 0 and 1 (0 < b < 1)
  • The guide covers appreciation, depreciation, and compound interest formulas
  • It contrasts exponential functions with linear functions and simple interest

I love this app so much [...] I recommend Knowunity to everyone!!! I went from a C to an A with it :D

Stefan S, iOS User

The application is very simple and well designed. So far I have found what I was looking for :D

SuSSan, iOS User

Love this App ❤️, I use it basically all the time whenever I'm studying

Exponential Functions and Compound Interest Study Guide

This comprehensive study guide explores the fundamental concepts of exponential functions and compound interest, providing essential information for students learning about growth and decay patterns in mathematics and finance.

Definition: Exponential functions are mathematical expressions based on multiplication patterns rather than addition.

The guide begins by emphasizing the crucial difference between exponential and linear functions, highlighting that exponential growth and decay are characterized by multiplicative changes.

Highlight: Exponential growth occurs when the multiplier bb in the function y = ab^n is greater than 1 b>1b > 1.

For exponential growth, the guide provides an example: y = 222^x, illustrating how the function increases over time. This concept is directly related to appreciation in financial contexts.

Example: In financial terms, if an asset appreciates by 6%, the multiplier used in the exponential function would be b = 1.06.

The study material also covers exponential decay, which occurs when the multiplier is between 0 and 1 0<b<10 < b < 1. An example given is y = 20.50.5^x, demonstrating how the function decreases over time. This concept is linked to depreciation in economics.

Example: For a 6% depreciation rate, the multiplier in the exponential function would be b = 0.94.

The guide provides the general formula for exponential functions: y = ab^n, where 'a' represents the starting value, 'b' is the base ormultiplieror multiplier, and 'n' is the exponent oftenrepresentingtimeoften representing time.

Vocabulary: In the context of finance, 'appreciation' refers to an increase in value over time, while 'depreciation' indicates a decrease in value.

The material distinguishes between simple interest and compound interest, noting that compound interest follows an exponential pattern. It also touches on linear functions y=mx+by = mx + b to contrast with exponential growth.

Highlight: When given two points on a graph, students are advised to use a system of equations to solve for the variables in the exponential function.

This study guide serves as a valuable resource for understanding exponential growth and decay examples with answers, providing a solid foundation for more advanced topics in mathematics and financial modeling.

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.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

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.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

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 app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
