"action": "image_generation", "action_input": "Two separate mathematical plots on a white background with clear axes. Left plot: y = x^3 + 3x^2 - 24x, a cubic curve starting from bottom-left, going up to a local maximum at (-4, 80), coming down through (0,0) to a local minimum at (2, -28), then going up to top-right. Right plot: y = 5x - 2x^2, a downward-opening parabola starting from (0,0), reaching a peak (vertex) at (1.25, 3.125), and crossing the x-axis again at (2.5, 0). Labels for axes and key points included."
