Answers vary, should mention how the function does not always have the same output for a given input. As pictured, the \(x\)-value \(3\) corresponds to more than one \(y\)-value. Determine whether this relation is a function or not, and find the values of both a and b. After that, check whether each input value has a corresponding out 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. Given a function rule, students will complete a table of values or given a table of values, students will find the function rule.Worksheet 4: Function rules and table of values 2Riddle. %PDF-1.3 % /Title ( I n f i n i t e A l g e b r a 1 - C o n t i n u o u s R e l a t i o n s) Then graph the function and its inverse.

It is NOT a function since two ordered pairs have the same domain or x-value. 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. 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 \(5\). endobj (b) {(2, 1), (4, 2), (6, 3), (8, 4), (10, 5), (12, 6), (14, 7)} is not a function. 0000001962 00000 n stream Illustrate the travelled distance in the form of function t in hours. 2. 0000000556 00000 n Applying for a job is more than just filling out an application. /SMask /None>> Introduction to New Material. so will it will not be a function because -4 will have to pair up with -3. >> In what year was the value of the car at a minimum?
