Vocabulary �Function – A relation in which each element of the domain is paired with exactly one element in the range. �Function Rule – The operation performed on the input of a function �Function Table – A table organizing the input, rule, and output of a function.

Vocabulary �Input – What you put into the function; the x value �Output – What comes out of the function; the y value

Example 1 Make a Function Table

Example 2 Make a Function Table

Example 3 Make a Function Table Make a function table for four different input values and write an algebraic expression for the rule. Then state the domain and range of the function. RULE: Double a number and subtract one

Notes �Functions are often written as equations with two variables – one to represent the input and one to represent the output

Example 4 Use Multiple Representations

Example 5 Use Multiple Representations An assembly line produces 30 boxes per hours. (a) Write an equation to find the amount of boxes it can produce for any number of hours (b) Make a function table for 5, 10, 15, and 20 hours of production. Then graph the ordered pairs.

Notes

Vocabulary �Independent Variable – The variable in a function with a value that is subject to choice �Dependent Variable – The variable in a relation with a value that depends on the value of the independent variable

Notes

Example 1 Determine whether a relation is a Function

Example 2 Determine whether a relation is a Function

Example 3 Determine whether a relation is a Function Determine whether each relation is a function. (a) { (3, 48), (7, 21), (5, 15), (1, 13), (2, 12)} (b)
