Whether you are analyzing a graph or algebraically manipulating formulas, it is necessary to identify the boundaries in which a function will have meaningful results.  ## A lot of happy customers

Amazing app it gave you all the good answers and if you didn't understand how they explained to you so it's basically amazing and probably better than most teacher's. Few ads in the free version, and no ads in priemium, i'm a student, of course I'm broke. I was about to fail in math, doing online school.

Update: I've had the app through pre and intermediate algebra and now pre calculus, it really helps. I recommend students who face difficulty in solving large calculation to install this app But It's so good that i don't want to use my brain….

Good interface. This is such a helpful app, and it's not just your average calculator, a plus all day, if you need steps then you have to pay. Also gives detailed steps and different ways of solving the given equations, though doesn't always show the way I would solve the equation as the application has a higher level lever of mathematics that it can apply which can theoretically be problematic if the user doesn't know what the app did to solve the equation.

## How to Find Domain and Range of a Function?

The domain of a function is the set of all values that hold true when plugged into the equation, whereas the range is all possible outputs of the equation depending on what values are plugged in. ## How to find domain and range of functions
