So aim to be able to recognise the equations and graphs of quadratics, cubics, reciprocals, exponentials and circles. The quadratic factorises to give \((x + 3)(x − 2)\) so the solutions of the ...

Horizontal lines have equations of the form \(y = c\). Draw the graph of \(x = 3\). Mark some points on a grid which have an \(x\)-coordinate of 3, such as (3, 0), (3, 1), (3, -2). The points lie ...
