Page 2: Relations and Functions

This section explores the fundamental concepts of relations and functions, focusing on domains, ranges, and the distinction between discrete and continuous relationships.

Definition: A function is a relation where each input x−valuex-value corresponds to exactly one output y−valuey-value.

Example: The set {5,35,3, 4,24,2, 3.1,13.1,1, 4,04,0} represents a discrete relation.

Highlight: The vertical line test determines if a relation is a function - if a vertical line intersects the graph more than once, it's not a function.

Vocabulary: Domain represents input values, while range represents possible output values.

ن Solving ine If asb then atc4b+c and a-c²b-c b=5 4*858213 4-865-8-4²-3 If asb then ² ac cbc * if we multiply or divide by a negitive #. nee

Page 3: Function Notation and Forms

This chapter covers function notation and different forms of linear equations, incorporating صيغة الميل والمقطع العامية concepts.

Definition: Standard form: Ax + By = C Point-slope form: y - y₁ = mx−x1x - x₁ Slope-intercept form: y = mx + b

Example: f22 = 2² + 222 = 4 + 4 = 8 demonstrates function evaluation.

Highlight: When converting between forms, ensure there are no fractions in standard form and no common factors.

ن Solving ine If asb then atc4b+c and a-c²b-c b=5 4*858213 4-865-8-4²-3 If asb then ² ac cbc * if we multiply or divide by a negitive #. nee

View

Page 4: Slope and Linear Relationships

This section focuses on slope calculations and linear relationships between points, including parallel and perpendicular lines.

Definition: Parallel lines have the same slope, while perpendicular lines have opposite reciprocal slopes.

Example: Calculating slope using m = y2−y1y₂-y₁/x2−x1x₂-x₁

Vocabulary: Scatter plot represents data points graphed as ordered pairs.

Highlight: Regression lines can be calculated using statistical tools to analyze data relationships.

ن Solving ine If asb then atc4b+c and a-c²b-c b=5 4*858213 4-865-8-4²-3 If asb then ² ac cbc * if we multiply or divide by a negitive #. nee

Page 5: Parent Functions and Domains

This page covers parent functions and their domains, essential for understanding دوال نطاق ومدى غير متصلة.

Definition: Domain represents x-values for which a function is defined, while range represents possible y-values.

Example: For fxx = √x, the domain is [0,∞) since square roots of negative numbers are undefined.

Highlight: Special attention must be paid to restrictions such as denominators equal to zero and negative values under square roots.

View

Page 6: Function Transformations

This final section explores various function transformations and their effects on parent functions.

Definition: Transformations include reflections, translations, stretches, and compressions.

Example: fxx = -|x| - 3 represents a reflection over the x-axis and a downward shift of 3 units.

Highlight: The order of transformations matters when applying multiple changes to a parent function.

Page 1: Complex Inequalities

This page introduces solving complex inequalities and understanding intersection and union concepts. The material covers essential techniques for handling compound inequalities joined by "and/or" operators.

Definition: Complex inequalities are mathematical statements containing two or more inequalities joined by logical operators AND/ORAND/OR.

Example: For inequalities like -3≤2x+5≤19, solve each part separately and then combine the solutions based on the logical operator.

Highlight: When multiplying or dividing by a negative number, the inequality sign must be flipped to maintain the correct relationship.

Vocabulary: Intersection represents the overlap of two sets, while union combines all elements from both sets.

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.

Samantha Klich

Android user

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.

Anna

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

Brad T

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🤍🤍

David K

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.😋🩷🎀

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!
