Answer:
y = [-3](x - [0])² + [0]
Explanation:
The general for is:
y = a(x - h)² + k
where (h, k) is the vertex
we have (h, k) = (0, 0)
so, y = a(x - 0)² + 0
y = ax²
The point plotted in the picture is : (1, -3)
This point lies on the parabola and hence satisfies y = ax²
⇒ -3 = a(1²)
⇒ a = -3
Therefoe, the parabola equation is:
y = -3x²
y = -3(x - 0)² + 0
