Question

Which of the following equations is of a parabola with a vertex at (0, 6)?

O y= (x - 6)2
O y= (x + 6)2
O y=x2-6
Oy= x2 + 6

Answer 1

y= x^2 + 6

Explanation:

y= x2 + 6 (which should be written as y= x^2 + 6) has the form y - k = a(x - h)^2. For y= x^2 + 6, h = 0 and k = 6. Thus the vertex is (0, 6)
