Thanks to devs, this is the best app for maths questions especially with algebra, this app is saving me so much stress, update: I've had the app through pre and intermediate algebra and now pre calculus.

I like how this app doesn't only solve basic math, easy to use, very helpful. Really efficient and accurate, wish I could give it 10 Stars, it is the best program. This app has saved me so many times with my homework, so simple and helpful.

Guy Cruz

It even explains how to get through the equations. Super helpful for solutions, but not so much explanations, great! Especially for a beginner like me, this is the best app it has helped me so much with my learning disability and it is helping me get my math homework done fast and easy and I love it and this is one of the best app I have ever had I want to get rid of the other apps that I've got and keep this one because it's going to help me get through everything thank you for making this app.

## 3.1 Functions A relation is a set of ordered pairs (x, y). Example

Functions Find Three Ordered Pair Solutions f (x) = −1 (x + 2) f ( x) = - 1 ( x + 2) Write f (x) = −1(x+ 2) f ( x) = - 1 ( x + 2) as an equation. y = −1(x+2) y = - 1 ( x + 2) Simplify −1(x+2) - 1 ( x + 2). Tap
