A cubic graph is produced when you have an equation of the form \(y = ax^3 + bx^2 + cx + d\), where \(b\), \(c\) and \(d\) can be zero but \(a\) cannot be zero. Cubic graphs are curved but can have ...

A function is a rule that is applied to one set of values to give another set of values. A function can be illustrated on a graph – points are plotted as coordinates and joined by either a straight ...

Try to solve the following maths problem: does x^3+y^2+1 produce the same form as x^3+3y^2+xy^2? For cubic equations, it’s possible to solve this problem, but mathematicians found things more ...
