These two number lines define a flat surface called a plane4, and each point on this plane is associated with an ordered pair5 of real numbers \((x, y)\). For instance, f(x) = root over x is an undefined function when the value of x is negative. It could also be used as a worksheet for homework. endobj Ex 5. (b) {(2, 1), (4, 2), (6, 3), (8, 4), (10, 5), (12, 6), (14, 7)} is not a function. It is a function since no two ordered pairs have the same domain or x-value. For example, the ordered pair \((4, 3)\) represents the position \(4\) units to the left of the origin, and \(3\) units above in the second quadrant.

A function, on the other hand, is a relation that produces one output for each given input. This is because humans get taller throughout time and then stagnate for a period. This will be put in as a formative assessment grade. 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. << Reflections Over Intersecting Lines as Rotations. /F9 9 0 R For relations consisting of points in the plane, the domain is the set of all \(x\)-values.

Use the graph to find the corresponding \(y\)-values where \(x = 8, 0\), and \(8\). \(f ( - 2 ) = - 7 , f ( 0 ) = - 3 , f ( x - 3 ) = 2 x - 9\), 7. This is because a person has just one height value at any time in their life. you CAN do math! Given the graph of \(g(x)\), find \(g(8), g(0)\), and \(g(8)\). We can use the given ordered pair solutions to estimate all of the other ordered pairs by drawing a line through the given points. As a check, we can evaluate \(f (4) = 5 (4) + 7 = 27\).

Functions and Relations Worksheet Decide whether the graph represents y as a function of x. Determine the domain and range of the following relation and state whether it is a function or not: \(\{(4, 3), (2, 6), (0, 3), (3, 5), (3, 7)\}\). The given relation is not a function because the \(x\)-value \(3\) corresponds to two \(y\)-values. For example: \(\begin{aligned} h ( \color{Cerulean}{4 a ^ { 3 }}\color{Black}{ )} & = \frac { 1 } { 2 } ( \color{Cerulean}{4 a ^ { 3 } }\color{Black}{)} - 3 = 2 a ^ { 3 } - 3 \\ h ( \color{Cerulean}{2 x - 1}\color{Black}{ )} & = \frac { 1 } { 2 } ( \color{Cerulean}{2 x - 1}\color{Black}{ )} - 3 = x - \frac { 1 } { 2 } - 3 = x - \frac { 7 } { 2 } \end{aligned}\).
