AI Drawing Prompt Reference
Draw the graph of a quadratic function by adjusting the values of a, b, and c. Find the roots of the function on the graph and annotate them. First, draw the function f(x) = ax^2 + bx + c, then find and mark the positions of the roots R_1 and R_2 on the graph.
The prompt above was compiled from the original drawing commands and is for reference only.
