GCSE Maths - What are Cubic Graphs & How to Plot Them #78

The video tutorial explains cubic graphs, highlighting their unique 'wiggle' and the necessity of an X^3 term in their equations. It discusses how the sign of the X^3 term affects the graph's direction and provides a step-by-step guide to plotting cubic graphs using a table of X and Y values. The tutorial emphasizes the importance of a smooth curve when connecting plotted points.

Describe the process of plotting a cubic graph using the equation y = X^3 + X - 2.
