Answer:b. The graph of the quadratic function y = ax^2 is a parabola. Its shape is symmetric with respect to its axis of symmetry, and it opens upwards if a > 0 or downwards if a < 0.c. As the value of a becomes larger (either positively or negatively), the parabola becomes narrower, meaning it is steeper and more compressed vertically.d. When 0 < a < 1, the parabola opens upwards but is wider and less steep compared to when a > 1. This indicates a slower rate of change in y as x moves away from the vertex.e. When a < 0, the parabola opens downward, indicating that the vertex represents a maximum point rather than a minimum. When a > 0, the parabola opens upward, with the vertex being a minimum point.Step-by-step explanation:
