Question

What is the v-value of the vertex?
f(x) = (x + 2)^2 - 1
-value of the vertex:​

Answer 1

Okay, I don't know what a V-value is, but I can get the vertex coordinates...

Explanation:

So, this is the basic formula for parabolas:

`f(x)=a(x-h)^(2)+k`

Now, your equation is this form, and the vertex of parabola's in this context is:

`(h,k)`

So, therefore:

`(-2,-1)` <------ANSWER

Hopefully this is a good explanation!
