In this case, we interpret f( 5) = 3 as follows: Figure 2.1.17 -2 Relation.

The students look at graphs containing dots and decide rather or not the dots form a linear or nonlinear relationship. Here we separate the domain (x-values), and the range (y-values), and depict the correspondence between the values with arrows. /Length 12 0 R Of special interest are relations where every \(x\)-value corresponds to exactly one \(y\)-value.

We can use the given ordered pair solutions to estimate all of the other ordered pairs by drawing a line through the given points. The ordered pair \((x, y)\) represents the position of points relative to the origin. Find \(f (12), f (0)\), and \(f (12)\). The students look at graphs containing dots and decide rather or not the dots form a linear or nonlinear relationship. Next, we define a relation9 as any set of ordered pairs. 9.

Title: Infinite Algebra 1 - Continuous Relations Created Date: Therefore, \(x = |y| + 1\) does not define a function. Given the graph, state the domain and range and determine whether or not it represents a function: From the graph we can see that the minimum \(x\)-value is \(1\) and the maximum \(x\)-value is \(5\). 2. Range: Function: o 2 t 3 3 (3, 3) -2) Relation . If asked to find \(x\) where \(f(x) = a\), we set the function equal to \(a\) and then solve for \(x\). But for the -4 the range is -3 so i did not put that in. PDF RELATIONS & FUNCTIONS Worksheet - School For Excellence 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. 12 0 obj 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.

This is a yes or no worksheet where the students look at 20 different graphs and use the vertical line test to decide rather or not they are a function. To define, a function is a binary process or relation that makes each element of one set somehow related to exactly one element from the second one. 0000000016 00000 n Here we can see that the graph of \(y=|x|2\) has a domain consisting of all real numbers, \(=(,)\), and a range of all y-values greater than or equal to \(2, [2,)\).
