Learn how to draw and interpret quadratic, cubic and exponential graphs and how to use quadratic graphs to solve equations.

At the point (or points) where two graphs intersect, the x and y values are the same for both functions. We use this information to find the solution to simultaneous linear equations.

It is inspired by Cardano’s solution of the cubic equation and Newton’s theorem on power sums, and yields an interpretation of generalized Lucas polynomials in terms of the theory of symmetric ...
