Question

Which of the following equations is of a parabola with a vertex at (0, -5)?

A: y = (x - 5)2
B: y = (x + 5)2
C: y = x2 - 5
D: y = x2 + 5

Answer 1

\(f(x)=y=(x-h)^2+k\) is a parabola with vertex at \((h, k)\)

Answer 2

the answer is B

Answer 3

no, the would mean the vertex was at (-5, 0).
