Question

What does the graph tell you about the value of k in this function?

Answer 1

k is less than 0? @SolomonZelman

Answer 2

We have found out that
1) n is even
2) a is greater than zero

Look at the x-coordinate of the minimum point (if I can refer to this (-5,2) with this name).

Answer 3

You know how to find the center in a equation like
y=(x - h)^2 +k

center: (h,k)

Answer 4

The k is just the x-coordinate of this that "center".

Answer 5

oh

Answer 6

n is even?
