Identify the vertex of y = x2 + 4x + 5.

(-2, 1)

Step-by-step explanation:

The vertex (h, k) of a parabola of the form is found by the formula , and then evaluating the parabola at to find .

We know from our parabola that and , so let's find :

Now, we just need to evaluate our function at to find . In other words, we just need to replace with -2 and simplify:

We can conclude that the vertex of our parabola is (-2, 1)
