📈 A Clever Way to Remember Key Graph Shapes: No Graph Sheet Needed! One of the biggest challenges students face in Pre-Calculus and Algebra is remembering how functions behave on a graph. So in today’s short tutorial, I showed a powerful memory trick: Instead of relying on a graph sheet, I simply drew the axes and used letters inside the function name to visualize the graph shape: SINE → hide the “N” → looks like a wave 🌊 → sinusoidal curve ABSOLUTE → zoom in on the “V” → sharp V shape on grap
