How to find the average rate of change of a function

Could give more stars to the app if possible, the only thing it's not really up to date on are word problems , at least I haven't figured out to make them work. Wonderful experience i wish we had an option to chose a photo from the gallery in our phones though. Only thing is we need to write down our problem on a piece of paper, this app will give you the solution in fraction of seconds along with the steps performed.

It's great for most Algebra 2 concepts, i can now get a 100% and know how I got it my tests, the app works very well and answers quickly. 5 stars to you at once. Easy, simple, gives you the answer, gives you opinions for how you want it to be solved.

Explains all the steps and why they took them. Best app ever to use for math problems, easy to use and accurate, it is so helpful and everyone who sees this app on the recommended area should try this out, so please DOWNLOAD this app if you want some help in your math problems.
