Example Draw the graph of y = x 2 x 4 and use it to find the roots of the equation to 1 decimal place. Draw and complete a table of values to find coordinates of points on the graph.

THE methods employed in this book, which presents an attractive appearance, are almost entirely independent of the aid of general mathematical principles. For instance, the form of tke graph of y ...

Quadratic graphs A quadratic graph is produced when you have an equation of the form y = a x 2 + b x + c, where b and c can be zero but a cannot be zero. All quadratic graphs have a line of symmetry.
