1. AGENDA WARM-UP LESSON 21 AND 22 CORRECTIONS LESSON 23 AND 24 HW QUESTIONS? LESSON 25 EXIT CARD

2. WARM-UP 1.Find the value of y when x = 8 5y = -3x – 6 2. Solve 0.45x – 0.002 = 8.098

3. LESSON 23 AND 24 HOMEWORK QUESTIONS??

4. LESSON 25: DIFFERENTIATING BETWEEN RELATIONS AND FUNCTIONS Recall: In an ordered pair (x, y), y depends on x. -independent-dependent -input values-output values

5. DETERMINING DOMAIN AND RANGE. Mapping Diagram Ordered Pair Table

6. RELATION VS. FUNCTION RelationFunction _ *Set of ordered pairs *each number in the domain is matched to one or more matched with EXACTLY members in the range one member of the domain

8. VERTICAL LINE TEST *used to determine if a relation is a function

10. GRAPH THE ORDERED PAIRS AND USE THE VERTICAL-LINE TEST TO SEE IF THE SET IS A FUNCTION

11. WRITING A FUNCTION Goal: Isolate the dependent variable (y) Ex: Write x – 3y = 4 in function form

12. Ava is collecting money for a charity and donating $12 of her own money. She asks friends to give $5 each. Write a rule in function notation to find how much she will donate in all.
