1. Function Rules

2. Function The relationship between the input and output values

3. Function Each input value has EXACTLY one output value

4. Function Function Notation: f(n) = n + 5 OutputInput

5. Function Function Notation: f(n) = n + 5 Rule for Function

6. Example F(x)2x+1 13 25 37 49 2(1)+1=3 2(2)+1=5 2(3)+1=7 2(4)+1=9

7. Function Example: You are driving a car 50 miles per hour (mph)

8. Function Example: D = r t d = 50t d=distance R= rate t=time

9. Function Set up a table using the previous function rule: d = 50 t Time(Input)12345 Distance(Output)

10. Function Find the Rule ~ Remember to define the variable. Look at next slide to see if you are correct Hours Worked Salary 1$6 2$12 3$18 4$24 5$30

11. Answer Define the variable s = salary h = hours Function Rule s = 6h s = 6h

12. Function Weeks Plant Height 13 25 37 49 511 Find the Rule ~ then look at next slide to see if you are correct

13. Answer Define the variable h = height w = number of weeks Function Rule h = 2 w + 1
