B. h < 0 and k < 0
C. h > 0 and k > 0
D. h > 0 and k < 0

Answer 1

I like these kinds of problems! The formula that is written above is in vertex form, meaning you can get the vertex point from the (h, k). What is your understanding of this question?

Answer 2

I know that A and C are not correct because they are greater than 0 while the graph has the k value less than zero. But the h value is the opposite right?

Answer 3

vertex form f(x) = a(x-h)^2 + k

Answer 4

Oh so the h value will have a sign change making what is positive, negative and negative, positive right?

Answer 5

Becuase of the exponent I believe.

Answer 6

So the answer would be D right?
