Fill in each table for the INPUTOUTPUT RULE

Fill in each table for the INPUT-OUTPUT RULE. 1) OUTPUT = 3 INPUT x y 0 1 2 3 4 2. Find the Input Output Function Input -1 -2 1 Output 0 -2 4 3. Determine if the following is a function Input -1 1 0 3 4 Output -2 4 1 4 3 Warm-up

In Class Example Does each relationship of the form (input, output) represent a function? If the relationship does not represent a function, find an example of one input that has two or more outputs. A. (city, zip code) B. (person, birth date) C. (last name, first name) D. (state, capital)

Unit 2 – Day 2 Functions Domain and Range

Vocabulary �Vertical Line Test : helps you determine whether a relationship is a function by looking at its graph. �If all possible vertical lines cross the graph only once (or not at all), then the graph is a function. �If even one vertical line crosses the graph more than once, the graph is not a function.

In Class Example- Determine if each is a function

Your Turn y y y x x x y y x x

Part II: Equations Graph the function and see if it passes the vertical line test. Examples: 1. y= 2 x+ 1 2. 3) 4. y=x^3+ 5

Domain and Range- Explain in your own words What is Domain? What is Range?

Let’s Practice State the domain and range of the following relation. Is the relation a function? {(– 3, 5), (– 2, 5), (– 1, 5), (0, 5), (1, 5), (2, 5)}
