Question

Which of the following equations is of a parabola with a vertex at (1, -2)?

Answer 1

Answer:

y = (x-1)^2 - 2

Step-by-step explanation:

The parabola vertex point is always (h, k) in y = (x-h)^2 + k

All you have to do is look at h and k to find your vertex. Since in y = (x-1)^2 -2 has an h of -1 (Which makes it positive 1 when you plug it in) and a k of -2, that means that is your answer.
