1. 1) Find the rate of change from 2 to 4 years. = 4 in / year Time (years) 123456 Height (in.) 273537434549 2) Find the domain and range of the data. D = { 1, 2, 3, 4, 5, 6 } R = { 27, 35, 37, 43, 45, 49 }

2. 1. x - 5 = -17 2. -3x + 12= -15 3. 20 – 3x = 17 4. = -10

3. 1)4 inches / year 2)m = -2 3)m = 2 4)m = 1

4. Math I UNIT QUESTION: How do we graph functions, and what can be done to change the way they look? Standard: MM1A1 Today’s Question: What properties of functions can we find by looking at a graph? Standard: MM1A1d

5. Domain and Range: Points Find the domain and range of the following: domain: {2, 3, 4, 6} range: {–3, –1, 3, 6} {(2, –3), (4, 6), (3, –1), (6, 6), (2, 3)}

6. Domain and Range: Graph Look horizontally: What x-values are contained in the graph? That’s your domain! Look vertically: What y-values are contained in the graph? That’s your range!

7. Domain and Range: Graph

10. Maximum and Minimum Maximum value: the highest y value seen in the data or on the graph. Minimum value: the lowest y value seen in the data or on the graph.

11. Max and Min: Table Time (years) 123456 # of Wins282423252126

12. Max and Min: Graph

13. What’s a zero? The x-intercept or the point where y = 0.
