Countdown to Exams - Day 51 - Reciprocal and Exponential graphs

In today's countdown, we take a look at the graphs of Reciprocal and Exponential functions. It is very important that you are able to distinguish between the shapes of the two graphs as you may be asked to fill in a table of values and plot the graph. If you know the shape, then you can check if your calculations are correct.

Make sure you know the key points of each graph and in an exam, check your answers so you do not lose simple marks.

Countdown to Exams - Day 50 - Quadratic and Cubic graphs

Today we take a look at Quadratic and Cubic graphs. It is important to understand the shape of these graphs and identify where they cross the x and y axes as you will be asked questions about this. Sometimes you will be required to fill in a table of values and then plot the graph. Take care plotting the points and always check the shape of your graph. If it is a quadratic, is it symmetrical?

It is always worthwhile double/triple checking your work here to ensure accuracy.

Countdown to Exams - Day 46 - Coordinates

Here we take at look at the first 'Graph' section. We start off fairly simply looking at coordinates. A set of coordinates provides us with a set of instructions that indicate the position of a point or object. They normally occur in pairs (x,y) where the first number is your direction along and the second value is your direction up/down.

You will need to be able to plot coordinate points accurately for many types of question as well as being able to read the points off a graph as well.
