Question

What is the vertex of the parabola whose equation is y = (x + 1) ^2+ 3

Answer 1

The vertex is (-1, 3)

Explanation:

The form this is in is called vertex form. We can express the equation using its base form.

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

Now we can identify the vertex as (h, k). By looking at the equation, we can see h is equal to -1 and k is equal to 3.
