Plotting your graph A quadratic equation is represented as a curve on a set of axes. In order to draw the curve on a graph we require several pairs of coordinates.

The plot function creates a 2D plot with the slope-intercept form of the equation, and the (x,-10,10) part specifies the range of the graph, between the x values of -10 and 10.

Quadratic equations are basic to algebra and are the math behind parabolas, projectiles, satellite dishes and the golden ratio.
