The equation below describes a parabola. If a is negative, which way does the parabola open?y = ax2
Question
The equation below describes a parabola. If a is negative, which way does the parabola open?y = ax2
Solution
The parabola opens downwards when the value of 'a' in the equation y = ax^2 is negative. This is because the sign of 'a' determines the direction in which the parabola opens. If 'a' is positive, the parabola opens upwards, and if 'a' is negative, the parabola opens downwards.
