The correct answer is:
A parabola opening up is graphed on a coordinate plane with vertex at (0, 0). Domain is labeled as (-∞, ∞) and the range is y ≥ 0.
Explanation:
For the function y = -6x^2, since the coefficient of x^2 is negative, the parabola opens downwards. The vertex of the parabola is at (0,0). The domain of the function is all real numbers (-∞, ∞) because the function is defined for all values of x.
Since the parabola opens downwards, the range of the function is y ≤ 0. So, the correct range is y ≤ 0.
