Question

What is the vertex of the parabola given by the equation y = x2 + 4? A. (2, 8) B. (-2, 8) C. (0, 4) D. (4, 0) E. (0, 0)

Answer 1

Vertex form is

$y = a(x-p)^2 + q$

We're practically in vertex form,

$y = 1(x - 0)^2 + 4$

That's a vertex at x=0, y=4, (0,4)

choice C

Answer 2

Answer would be choice C
