Finding the rule

Today we looked at findng the rule from tables if you have already identified the relationships type.
Here are the notes. Make sure you make the connections between intercepts and rules as this is the first step to solving.

5 function introduction

Here are the class notes for the indentification of the 5 functions required for the 2CD course. You need to recognise them in table, graph and equation form.

Make sure you are familar with the terminology for the functions, particularly asymptotes and ratios

functions

This is the first instalment on sites to try and look at for functions. I will put the class notes up on the blog by Wednesday when we have finished them.

Comsider having a look at the khan learning academy. It is a series of videos that J and S have been watching to get another point of view.

this website is good for exploring and investigating the effects for transformations. It is American so reciprocal graphs are rational functions

look for yout tube clips as well.

Indices

here are the class notes on indices, consider learning the squares, cubes, powers of 2 & 3 as this helps later when solving equations in the non calculator papers
