EVERYONE ELSE PUT A CHECK NEXT TO A RIGHT ANSWER OR CORRECT IT!

2 Objective & Essential Understanding OBJECTIVE: SWBAT demonstrate their mastery of relations, functions, and functions graphing. ESSENTIAL UNDERSTANDING: Most mistakes in graphing functions are in calculating the coordinates! BC!!!!! We are entering algebra! Its Very Exciting!

3 Whiteboard Problem #1 What is the difference between Domain and Range? What determines if a Relation is a Function? Silently think about the answer & jot down your ideas

4 Whiteboard Problem #2 Map the following range and domains in a range table. Is this a function? Why? (2,3) (-1, 5), (3, 3), (4, 8), (0, 0) Silently think about the answer & jot down your ideas

5 Whiteboard Problem #3 Map the following range and domains in a range table. Is this a function? Why? (2,3) (-1, 5), (2, -3) (0, -4), (1, 6) Silently think about the answer & jot down your ideas

6 Whiteboard Question #4 Draw up a coordinate table and graph: Y = X + 3. Have at least three coordinate points. Silently think about the answer & jot down your ideas

7 Whiteboard Question #5 Draw up a coordinate table and graph: Y = 2X. Have at least three coordinate points. Silently think about the answer & jot down your ideas

8 Whiteboard Question #6 Draw up a coordinate table and graph: Y = 3X - 1. Have at least three coordinate points. Silently think about the answer & jot down your ideas

9 Whiteboard Question #6 Draw up a coordinate table and graph: Y = 3X - 1. Have at least three coordinate points. Silently think about the answer & jot down your ideas

10 Whiteboard Question #7 What is the domain and range of this relation? Is it a function? (-2, 3) (-1, 8), (2, 4), (3, 3), (-2, 8) HINT: To find the relations’s range, order it from low to high. Same for the domain… Silently think about the answer & jot down your ideas

11 Whiteboard Question #8 Draw up a coordinate table and graph: Y = ½ x + 2. Have at least three coordinate points. Silently think about the answer & jot down your ideas
