For Algebra II. This is a four-dimensional graph, expressed in two dimensions. I could have made it appear in three, but I didn't have the patience to learn how to make a 3D renderer for this. The equation used is ax^2 + bx + c. The color represents the value of the imaginary portion of y. Stated points are rounded to the nearest hundredth. This graph, including the grid and gradient, is drawn with pen blocks.
