Cubic and Reciprocal Graphs
You might need to draw or interpret cubic and reciprocal graphs in your exam
You can use a table of values to draw any graph, but it helps if you know what the general shape of the graph is going to be
Graphs that contain an x^3 term and no higher powers of x are called cubic graphs
Here are two examples
Graphs of the form y = k/x where k is a number are called reciprocal graphs
Here are two examples 
The graphs get closer and closer to the x-axis and y-axis but never touch them
With a cubic graph if you recognise the shape of the graph then it’s easier to tell if you’ve plotted your coordinates correctly
