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. Write an equation to find the amount of boxes it can produce for any number of hours 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. { (3, 48), (7, 21), (5, 15), (1, 13), (2, 12)}
