The Range (Statistics)

For f(x) = x 2, the domain in interval notation is: D: (-∞, ∞) D indicates that you are talking about the domain, and (-∞, ∞), read as negative infinity to positive infinity, is another way of saying that the domain is all real numbers. The range of f(x)

It is a great app! If I have problems in maths I just scan the exercise with the integrated camera function and the app solves the exercise for me. I used this app to see if my answers are wrong but turns out they're all correct, instructive and helpful! An USEFUL application for students.

A great thankx to This app inc. But overall it was great good explaination, many solutions, however this is one of the best math problem help apps for android. Appreciate it! Great work, its very helpful for when you cant find the answer (or just dont want to do it) my only complaint is having to pay for part of it to get the whole experience, but thats understandable.
