1. DELTA TABLES

2. What are they?  Delta tables are a way to determine what kind of function you are dealing with  If a function is a linear function, you will see the same number being added/subtracted every time

3. Examples – Are these functions linear? XF(x)∆ 1 05 19 213 317 421 XF(x)∆ 16 012 110 29 34 41

4. Examples – On your Own XF(x)∆ 27 022 117 212 37 42 XF(x)∆ 1 03 10 27 34 45

5. COMPOSITE FUNCTIONS

6. What are they?  Composite functions are when we find the output for one function and then that output turns into the input for another function  Remember to work from the inner parenthesis out

11. What is it?

12. Finding slope on a graph

13. A few notes  The graph that has the bigger number (regardless of sign) has the steeper slope  You may need to convert your fraction slope to a decimal in order to see which one is larger

14. Which has a steeper slope
