Question

In the parabola y = (x + 1)2 + 2, what is the vertex?
(1-2)
(-1,-2)
(1.2)
(-1,2)

Answer 1

In order to find the vertex of the given parabola, let's compare its equation with the vertex form of the quadratic equation:

$y=a(x-h)^2+k$

Looking at the given equation, we have h = -1, k = 2 and a = 1.

Since the vertex coordinates are given by (h, k), so the vertex coordinates are (-1, 2), therefore the correct option is the fourth one.
