Domain and range of composite functions calculator - CÔNG TY TNHH ...

That is, the maximum set of value for which the function exists. Sometimes the maximal domain is R (e.g. for y=x²). Sometimes the maximal domain is R+ (e.g. for y=log(x)) Sometimes the maximal domain is restricted to a set of values [0,∞) (e.g. the domain for which y=x² has an inverse) When do you need to find the maximal domain? ................
