The graph of a quadratic polynomial $y = ax^2 + bx + c$ is a parabola. If $a > 0$, the parabola opens:
(a) Upwards
(b) Downwards
(c) Towards the left
(d) Towards the right
Step-by-Step Solution
Key Concept: For $a > 0$, the parabola opens upwards. For $a < 0$, it opens downwards.
By geometric property of quadratic graphs, $a > 0$ implies an upward opening parabola. [1.0 Mark]
