WEBFunctions 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 domains are more limited.

WEBA function which varies for different parts of the domain, so the domain is divided into segments, and each segment could have a different function. One of common ones is stair step function with domain 0≤x<1 y=1. 1≤x<2 y=2, 2≤x<3 y=3, etc. which looks like a stair step without the vertical components. ( 3 votes)

WEBIn mathematics, the domain of a function is the set of inputs accepted by the function. It is sometimes denoted by or , where f is the function. In layman's terms, the domain of a function can generally be thought of as "what x can be". [1] More precisely, given a function , the domain of f is X.

WEBThe domain of a function includes all real input values that would not cause us to attempt an undefined mathematical operation, such as dividing by zero or taking the square root of a negative number. The domain of a function can be determined by listing the input values of a set of ordered pairs.

WEBDomain: The function. f(x) = x 2 + 2 . is defined for all real values of x (because there are no restrictions on the value of x). Hence, the domain of `f(x)` is "all real values of x". Range: Since x 2 is never negative, x 2 + 2 is never less than `2` Hence, the range of `f(x)` is "all real numbers `f(x) ≥ 2`".

WEBThe domain and range of a function is all the possible values of the independent variable, x, for which y is defined. The range of a function is all the possible values of the dependent variable y. In other words, the domain is the set of values that we can plug into a function that will result in a real y-value; the range is the set of values ...
