Answer:

Step-by-step explanation:
Standard form:

Vertex form:

(h, k) is the vertex
x is the coordinate of the vertex
To find x use the formula:


a=1
b=-2
c=-6
Substitute:

Substitute x in equation:

h=1
k=-7
Substitute h, and k into the vertex formula:

I can't see images.
Can you tell me what is looks like?
The answer is 27 because the are nine options which can be recombined in 3 independent ways. Therefore, 9*3=27
