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 ...

Curved graphs can be used to solve equations. The points at which the curve crosses a particular line on the graph are the solutions to the equation. If we want to solve the equation ...

Saving equations in a calculator can be useful for many reasons. You may want to store equations in a calculator so they can be graphed. You may also want to save an equation so you can see what you ...
