This worksheet can be used to teach/practise the required knowledge and skills expected at A level for the intersections of graphs.
The introduction discusses the different methods that can be used but then focuses on the method of substitution. There are then a few examples to illustrate the method, including questions about the geometrical interpretation of the answers.
The final section shows how the discriminant can be used to determine/show the number of points of intersection, with examples to illustrate the method.
Fully worked solutions to all examples are provided.
