This webpage checks how well you understand cubics, i.e. graphs of third degree polynomial equation y = ax^3+bx^2+cx+d. If the cubic has three real roots, the equation can be written in the form y=a(x-p)(x-q)(x-r). Below is a graph for specific values of a, p, q, r. Your aim is to find these values and plot the graph of the same function.
