Evaluate the function when x = 3, x = 0, and x = -2. It is NOT a function since two ordered pairs have the same domain or x-value. This is because humans get taller throughout time and then stagnate for a period. \(g (10) = 10\) and \(g (5) = 10 ; g (5) = 5\) and \(g (10) = 5\). Domain and Range Worksheets. 14 0 obj -2 Relation. 1A system with two number lines at right angles specifying points in a plane using ordered pairs \((x, y)\). The first number is called the \(x\)-coordinate, and the second number is called the \(y\)-coordinate. Domain: {3, 6, 9, 12}; Range: {-4, 0, 4} Mapping Diagrams: given a mapping diagram of a relation, we can tell if it is a function if each input is paired with exactly 1 output. Special relations where every \(x\)-value (input) corresponds to exactly one \(y\)-value (output) are called functions. A function is a relation in which each element of the domain is paired with EXACTLY one element of the range. Example: Decide whether the following relations are a function. Yes 4. We can visually identify functions by their graphs using the vertical line test15. Students will determine if the given relations (shown in mapping diagrams, function tables, graphs, and pairs of points) are a function or not. /SMask /None>> /Pages 3 0 R This is a coloring activity for a set of 12 problems on identifying the domain and range for a relation. 6 .

Print a copy of the Answer Key: Think FUNCTIONally printable for your use. /CSp /DeviceRGB Often, we can determine the domain and range of a relation if we are given its graph. The relation is a function because each x-value corresponds to exactly one y-value. Plus each one comes with an answer key. We have determined that the set of solutions to \(y = |x| 2\) is a function; therefore, using function notation we can write: \(\begin{aligned} y & = | x | - 2 \\ \color{Cerulean}{\downarrow} & \\ f ( x ) & = | x | - 2 \end{aligned}\). {(2, 1), (5, 1), (8, 1), (11, 1), (14, 1), (17, 1)} is a function also.
