The graph of a quadratic function resembles which letter?

Explanation:
Quadratic functions create a parabola when graphed. This smooth, symmetric curve forms a U shape when it opens upward, with a lowest point called the vertex. Since most quadratics have a > 0, the graph rises on both ends, matching the letter U. The other shapes don’t fit: a sharp V is two straight lines, a W would have two bumps, and an X is two crossing lines. So the graph resembles the letter U.
