The domain and range of the function. Functions are a correspondence between two sets called the domain and the range when defining a function you usually state what kind of numbers the domain x and range f x values can be but even if you say they are real numbers that doesn t mean that all real numbers can be used for x it also doesn t mean that all real numbers can be function values f x. In this case there is no real number that makes the expression undefined. F x is maximum at x 0 f x 4.
The domain is all values of that make the expression defined. Arithmetic mean geometric mean quadratic mean median mode order minimum maximum probability mid range range standard deviation variance lower quartile upper quartile interquartile range midhinge.
