Determine the domain and range of the following relation and state whether it is a function or not: \(\{(1, 4), (0, 7), (2, 3), (3, 3), (4, 2)\}\). There are 9 questions total.The first 3 questions give the student a mapping, a table and a set of ordered pairs and ask them to determine if the relations are functions or not and to find the domain and range of each.

The monthly income in dollars of a commissioned car salesperson is given by the function \(I(n) = 350n + 1,450\) where \(n\) represents the number of cars sold in the month. Functions and Relations Worksheet Decide whether the graph represents y as a function of x. A function, on the other hand, is a relation that produces one output for each given input. Here we are asked to find the x-value given a particular y-value. /SA true Are you getting the free resources, updates, and special offers we send out every week in our teacher newsletter? What are the Types of Functions in Mathematics? /CSp /DeviceRGB What was the value of the car when it was new in \(1970\)? Save my name, email, and website in this browser for the next time I comment. As pictured, the \(x\)-value \(3\) corresponds to more than one \(y\)-value. Ans. For the case of a function, a well-defined function will provide the same result if the input representation is altered, but the input value will not be changed. (b) {(2, 1), (4, 2), (6, 3), (8, 4), (10, 5), (12, 6), (14, 7)} is not a function. Often, we can determine the domain and range of a relation if we are given its graph. 2The horizontal number line used as reference in a rectangular coordinate system. A vertical line can cross the graph of \(x=|y|+1\) more than once; therefore, it is not a function.

Find \(f ( 0 ) , f ( 2 )\), and \(f ( 4 )\). There is exactly one output for every input. Substitute \(f (x)\) with \(27\) and solve. We have determined that the set of solutions to \(y = |x| 2\) is a function; therefore, using function notation we can write: \(\begin{aligned} y & = | x | - 2 \\ \color{Cerulean}{\downarrow} & \\ f ( x ) & = | x | - 2 \end{aligned}\). /CreationDate (D:20220708141653-04'00') Domain: \(\{5\}\); range: \(\{ 0,2,4,6,8 \}\); function: no, 7. The students will crea, In this concept-building, evaluating and identifying functions discovery worksheet, students will be able to evaluate functions for specific values; represent relations as a set of ordered pairs, table, graph, and mapping; and identify functions versus relations. %%EOF
The given relation is not a function because the \(x\)-value \(3\) corresponds to two \(y\)-values. 13. The representation of a relation on a rectangular coordinate plane, as illustrated above, is called a graph10. An expression is considered to be unambiguous or well-defined when the definition of the same allocates a unique value or interpretation. Relations and Functions Worksheet (with Answer Key + PDF) A relation is any set of ordered pairs. As every value of x has a different value of y; it is a function. Students will determine if the given relations (shown in mapping diagrams, function tables, graphs, and pairs of points) are a function or not. Free worksheet(pdf) and answer key on distinguishing functions from relations, stating domain and range and more. >> Functions and relations worksheet answer key | Math Assignments This compilation of domain and range worksheet pdfs provides 8th grade and high school students with ample practice in determining the domain or the set of possible input values (x) and range, the resultant or output values (y) using a variety of exercises with ordered pairs presented on graphs and in table format. 7.
