Functions assign outputs to inputs. The domain of a function is the set of all possible inputs for the function. For example, the domain of f (x)=x² is all real numbers, and the domain of g (x)=1/x is all real numbers except for x=0. We can also define special functions whose
I experienced no problems with this app, and its easy to use, straight to the point solutions and it really did helped me step forward in understanding maths. If I could I would rate it 1000/5, buts its worth it, honestly best app for tests and homework.
According to me it is the best mathematics app, I ever used. Use the take a picture feature a lot. This app has allowed me to practice my math and additional problems and check the answers to make sure I am doing it correctly.
You point a camera at a non-trivial math problem - handwritten, smudged with coffee - and it gives you back a step by step solution, definetly better than the last time i used it which was about a few months ago. The steps help with figuring out how to do the problems, I eventually was able to get through most of my problems with out it, but it is a good way to check all of your work.
State the domains of the following functions using inequalities. 1. f (x) = x 2 2. g (x) = √x 1. x 2 is a polynomial that is defined for all x values, so its domain is -∞ < x < ∞. 2. √x is an even root, so
