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

1. x - 5 = x + 12= – 3x = = -10

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

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

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)}

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!

Domain and Range: Graph

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.

Max and Min: Table Time (years) # of Wins

Max and Min: Graph

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