Question

6.

Identify the vertex of the parabola.



A. (−4, 0)

B. (−3, 1)

C. (1, −3)

D. (−1, −3)

Answer 1

B. (−3, 1)

Explanation:

-3, 1 is the vertex I believe

-3,1 should be the one

Answer 2

Explanation:

the vertex is the point, where the parabola turns around. it is (depending on its orientation, if it is opening upwards or downwards) the maximum or the minimum of the curve.

so, as we can see on the grid, that point is x = -3, y = +1 = (-3, 1).

so, B is correct
