Linear and Non-linear Functions

Linear functions, non-linear functions..who cares!  Well if you like good grades in algebra then you want to take “care” on understanding the differences between various functions.  Linear functions are lines and non-linear functions are other shapes like parabolas.  As long as you have a basic idea of the different type of functions you will be in good shape.

 

Key concepts to remember:

* lines are “linear functions”
* all other non-line graphs are “non-linear” functions

 

 

some key topics that involve linear and non-linear functions:

* best fitting lines and scatter plots
* quadratic functions
* exponential functions
* logarithmic functions
* absolute value functions
* polynomial graphs
* conic sections
