AI Drawing Prompt Reference

Draw the iteration process for finding roots of a polynomial. Start by taking a point A on the x-axis, then iteratively find the roots by drawing a horizontal segment connecting the current x-value to the function value, and a vertical segment connecting the function value to the x-axis. Repeat this process until all roots are found.
