Question

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

Answer 1

The "center" here is (-5,2).
(Not a center in this, but a minimum point)

So the k is ?

Answer 2

equal to zero?

Answer 3

no, what is the minimum point (The point with the smallest y and x value) ?

Answer 4

-5,2?

Answer 5

yes, so the k is?

Answer 6

greater than zero?

Answer 7

(referring to a parabola, where y=a(x-k)+c with center of (k,c) )

Answer 8

(forgot ^23 next to (x-k) sorry.

or, in a parabola, y=a(x+k)^2 +c

center is (-k,c)

Answer 9

look at the minimum point

Answer 10

I'm confused

Answer 11

do you see the point of (-5,2) on the graph ?

Answer 12

Yea

Answer 13

you are missing the dashed part for it to be a parabola
and the center in this case would be (k,c)

Answer 14

as we know that in
y=a(x+k)^2+c
the center is (k,c)

you can see the center on the graph, and take the k, or the x-coordinate of the center from it.

Answer 15

(I suck at explaining -:( )

Answer 16

it's ok lol so k is even/

Answer 17

k=-5

Answer 18

so less than zero
