Question

What is the vertex of a parabola whose equation is y = (x - 3)2?
(-3, 0)
(0, -3)
(0, 3)
(3, 0)

Answer 1

y-h=(x-k)^2

(h,k) is the vertex

Answer 2

y = x^2 - 3 - 1
y = x^2- 3
y =x + 2 - 9
vertex: (0 , -3)

Answer 3

Vertex of a quadratic function of the form y=a(x-h)^2 +k is at (h,k). This problem follows the pattern, so the vertex is also the x intercept at (3,0).
