Domain Of A Function As An Inequality
The example below shows two different ways that a function can be represented.
Domain of a function as an inequality. For more on inequalities see inequalities. Interval values represented on a number line can be described using inequality notation set builder notation and interval notation. As a function table and as a set of coordinates.
The range of a function is all the possible values of the dependent variable y. The domain of a function can be determined by listing the input values of a set of ordered pairs. The domain of a function can also be determined by identifying the input values of a function written as an equation.
The domain and range of a function is all the possible values of the independent variable x for which y is defined. All i did was to build up the function f x 2x 7 step by step starting with x and work with the inequality as i went to obtain an inequality equivalent to x 0. As an inequality we would write read as the domain of the function is all values of x which are greater than or equal to zero.
For example if we take the linear function. In so called interval notation the same function has a domain of this describes the set of values from 0 to positive infinity. The domain of a function can be determined by listing the input values of a set of ordered pairs.
The domain of a function can also be determined by identifying the input values of a function written as an equation. Interval values represented on a number line can be described using inequality notation set builder notation and interval notation. For this quiz and worksheet combo you are reviewing the domain and range of functions with inequalities.
Domain is the set of all x values the independent quantity for which the function f x exists or is defined. There are other ways one might approach the problem of finding the domain of a restricted linear function.
