Question

What are the coordinates of the vertex of the table? I X Y 0 1 -1 -2 -2 -3

Answer 1

We observe that the function is a parabola that grows upwards.
 For this case, we must first graph the function to observe the behavior of the same.
 We see that the vertex of the function is located at the point:
 (x, y) = (- 2, -3)
 The point is a minimum.
 Answer:
 (x, y) = (- 2, -3)
 It is a minimum.

Answer 2

(The vertex formula is derived from the completing-the-square process, just as is the Quadratic Formula. In each case, memorization is probably simpler than completing the square.) For a given quadratic y = ax2 + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k
