Which values for h and k are used to write the function f(x) = x^2 + 12x + 6 in vertex form?
h=6, k=36
h=-6, k=-36
h=6, k=30
h=-6, k=-30

The vertex is (-6,-30).

The vertex is usually written as (h,k) in most American schools I think.[

So h=-6 and k=-30.

Step-by-step explanation:

The given is in standard form, , where ,, and .

There is a formula for computing the vertex while the given is in standard form which is:

.

So let's start with the x-coordinate there:

.

Now the y-coordinate of the vertex can be found by replacing your x's in:

with -6.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
