Question

Which values for h and k are used to write the function f(x) =

XP + 12x + 6 in vertex form?
Oh=6, K-36
Oh-6, 2-36
Oh=6,30
Oh-6, 6-30

Answer 1

h = -6, k = -30.

Explanation:

Vertex form is a(x - h)^2 + k

f(x) = x^2 + 12x + 6

f(x = (x + 6)^2 - 36 + 6

f(x) = (x + 6)^2 - 30

So comparing with the above general for:

h = -6 and k = -30.
