What is the vertex of the parabola graphed below?
-4-2 o
2 4
(2,0)
(2,-4)
0 (-4,0)
(4,0)

Step-by-step explanation:

The vertex is either the highest point on the parabola or the lowest point. We have a positive parabola, so the vertex is a low point. It sits at (2, -4). Locate that point and see what I mean by the lowest point on the parabola.

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
