DELTA TABLES

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

Examples – Are these functions linear? XF(x)∆ XF(x)∆

Examples – On your Own XF(x)∆ XF(x)∆

COMPOSITE FUNCTIONS

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

Examples

RATE OF CHANGE

What is it?

Finding slope on a graph

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

Which has a steeper slope
