The domain of a function or relation is the set of all possible independent values the relation can take. It is the collection of all possible inputs. The range of a function or relation is the set of all possible dependent values the relation can produce from the domain values.

The domain is the set of the first coordinates of the ordered pairs. D={2,3,4,5,6} Next identify the output values. The output value is the second coordinate in an ordered pair. The range is the set of the second coordinates of the ordered pairs.

Definition of Range Range: The range is the set of all possible output values (commonly the variable y, or sometimes expressed as f(x) ), which result from using a particular function. When you have a function where y equals a constant, your graph is a truly horizontal line, like the graph below of y=3 .

The domain of a function in slope-intercept form is all real numbers. The domain of a function, f(x), is the set of all values of x that we can plug…

The domain of a function is the set of all possible inputs, while the range of a function is the set of all possible outputs.

1. The structure of a function determines its domain and range.
2. Here’s the graph of f(x)=x^{2}.
3. When the quadratic functions are in standard form, they generally look like this: f(x)=ax^{2}+bx+c.

For values of x for which y is negative, the graph of | y | is a reflection on the x axis of the graph of y. (see graph below). Check that the range is given by the interval [0 , +infinity), the domain is the set of all real numbers, the y intercept is at (0 , 2) and the x intercept at (2, 0).

The range is the set of all outputs for the function, which on a graph is the set of all possible y values. For intercepts, you look for where in the function either x or y will be zero. When x=0, that’s the y intercept. When y=0, that’s an x intercept.

The range is the set of y-values used in the relation. You can describe the range of a set by just listing the y values of all the ordered pairs in the set.
