### Writing linear functions edmodo

1. 1. Functions Unit 4 Part 2MCC8.F.3 Interpret the equation y = mx + b as defining alinear function, whose graph is a straight line; give examplesof functions that are not linear. For example, the function A =s2 giving the area of a square as a function of its side length isnot linear because its graph contains the points (1, 1), (2, 4),(3, 9), which are not on a straight line.
2. 2. What are the next three numbers in the list?• 1, 2, 3, 4, 5, … 6, 7, 8• 7, 9, 11, 13, 15, … 17, 19, 21• 2, 4, 7, 11, 16, … 22, 29, 37• 0, 1, 4, 9, 16, 25, … 36, 49, 64• 10, 7, 4, 1, -2, … -5, -8, -11
3. 3. Some Special patterns• Arithmetic 1, 2, 3, 4, 5, … 7, 9, 11, 13, 15, …• Geometric 1, 3, 9, 27, 81, … 32, 16, 8, 4, 2, …• Fibonacci 1, 1, 2, 3, 5, 8, …

14. 14. Graph an arithmetic sequence.1 2 3 4 51 2 3 4 5 Is this a function? What equation would model this data? y=x
15. 15. Graph this sequence.1 2 3 4 57 9 11 13 15 Is this a function? What equation would model this data? y = 2x+5
16. 16. Functions Unit 4 Part 3CC8.F.2 Compare properties of two functions each represented in adifferent way (algebraically, graphically, numerically in tables, or by verbaldescriptions). For example, given a linear function represented by a table ofvalues and a linear function represented by an algebraic expression,determine which function has the greater rate of change.*Comparing properties of two functions each represented in a different waywill be addressed in Unit 5. In this unit we will focus on representing thesame function different ways (algebraically, graphically, numerically intables, or by verbal descriptions), and identifying the unit rate of change.
17. 17. Relations and Functions• We will look at functions in four different ways1. Numerically; tables and ordered pairs2. Graphically3. Verbally4. Algebraically

Fill out a table, create a graph, and write an equation to modelthe money you will spend each month on your cell phone.
