Answer:
Okay, I don't know what a V-value is, but I can get the vertex coordinates...
Step-by-step explanation:
So, this is the basic formula for parabolas:
[tex]f(x)=a(x-h)^{2}+k[/tex]
Now, your equation is this form, and the vertex of parabola's in this context is:
[tex](h,k)[/tex]
So, therefore:
[tex](-2,-1)[/tex] <------ANSWER
Hopefully this is a good explanation!
