A function is a relation in which each element of the domain is paired with EXACTLY one element of the range. Consider the relations consisting of the seven ordered pair solutions to $$y = |x| 2$$and $$x = |y| + 1$$. The relation is a function. Set P = {-2,0,2} and the remaining elements are { (-2,-2), (-2,2), (0,-2), (0,0), (2,-2), (2,0), (2,2)} 2.

The rectangular coordinate system1 consists of two real number lines that intersect at a right angle. The argument can be any algebraic expression. stream The domain of the graph of $$x=|y|+1$$ consists of all x-values greater than or equal to $$1, [1,)$$, and the range consists of all real numbers, $$=(,)$$. Each one has model problems worked out step by step, practice problems, as well as challenge questions at the sheets end. Conduct an Internet search for the vertical line test, functions, and evaluating functions. /PCSp 5 0 R trailer Plus each one comes with an answer key. A relation is a set of one or more ordered pairs. This relation is not a function. For instance, f(x) = root over x is an undefined function when the value of x is negative. The Vertical Line Test: Given the graph of a relation, if a vertical line can be drawn that crosses the graph in more than one place, then the relation is not a function. The maximum $$y$$-value is $$3$$ and the minimum is $$3$$; hence, the range consists of $$y$$-values in the interval $$[3,3]$$. If any of the x values are repeated, but the values that correspond to them in the y-axis are different, then we are dealing with a relation rather than a function. 1 0 obj /F8 8 0 R WORKSHEET 7.4 INVERSE FUNCTIONS Inverse Relations Find the inverse for each the inverse for each relation below (put your answer on the same graph). <>>> Domain and Range Worksheets.

Free worksheet(pdf) and answer key on distinguishing functions from relations, stating domain and range and more. Algebra frequently involves functions, and so the notation becomes useful when performing common tasks. We can easily determine whether or not an equation represents a function by performing the vertical line test on its graph. $$g ( - 5 ) = 25 , g ( \sqrt { 3 } ) = 3 , g ( x - 5 ) = x ^ { 2 } - 10 x + 25$$, 11. >> Example 5: Solve the equations for y to determine if the equation defines a function.
