Answer 3

howd you get that?

Answer 4

+4

Answer 5

shld be 4

Answer 6

how do you get that?

Answer 7

remember... symmetrical line of curve

Answer 8

`h` is the x coordinate of vertex (turning point)

Answer 9

`k` is the y coordinate of vertex (turning point)

Answer 10

so it is 4?

Answer 11

Yes ! the graph is turning at (4, -2)
so h = 4
k = -2

Answer 12

oh ok I got h and k mixed up :D thanks!

Answer 13

Start with the standard equation:
f(x)=a(x-h)+k
when h>0, the vertex moves to the Right.

Answer 14

And (h,k) is the vertex.
