The parabola opens down because a < 0 option (B) Down is correct.
What is a parabola?
It is defined as the graph of a quadratic function that has something bowl-shaped.
We have an equation for the parabola:
y = -3x²
The standard form of the parabola:
y = a(x -h)² + k
If a > 0 (parabola opens up)
If a < 0 (parabola opens down)
Here a = -3
-3< 0 (opens down)
Thus, the parabola opens down because a < 0 option (B) Down is correct.
