Question

What is the equation of the following graph in vertex form?

Answer 1

Lets see the graph :)

Answer 2

and here are my answer choices! :-)
y = (x − 2)2 + 1
y = (x − 1)2 + 2
y = (x + 2)2 + 1
y = (x + 2)2 − 1

Answer 3

Vertex form is given by the formula, y=a(x-h)^2+k right?
Well the Point where the graph is at the highest is the vertex.
So (h,k) is the vertex. in this case (2,1) is the vertex. So can u plug those into y=a(x-h)^2+k?

Answer 4

@YoloShroom yes, and I got y=(x+2)2-1

Answer 5

It's +k :) so it's y=(x-2)^2+1 :)

Answer 6

oh ok, so thats all I had to do to d=solve that problem?

Answer 7

could I have help with on more similar please?

Answer 8

I believe so.
It didnt ask you to solve for A so i think that's where it ends. If you need to solve for A though, you can plug in.

And yes please! open a new thread and post!
