About the Course

In this course, Professor Keith Ball (University of Warwick) continues exploring graphs, covering Topics A11-A12 in the Pearson Edexcel GCSE (9-1) Mathematics Specification for Foundation Tier. In the first mini-lecture, we introduce quadratic functions, discuss how the various terms and their coefficients affect the shape of the corresponding graph, and take a look at turning points (Topic A11). In the second mini-lecture, we consider the roots, or solutions, of quadratic equations and consider graphs where there are two roots, one root, or zero roots (Topic A11). In the third mini-lecture, we consider the graphs of cubic functions and look at cubic graphs with three roots, two roots, or one root (Topic A12). Finally, in the fourth mini-lecture, we explore the graph of the reciprocal function (Topic A12).
