i would find the co-ordinate of the minimum point for that function!

mertsj · Answer

Find the vertex by using x = -b/2a

anonymous · Answer

What is a co-ordinate?

anonymous · Answer

a point*

mertsj · Answer

Then plug that answer into the equation to find y.  That will be your vertex.  Pick the graph that has that x and y value.

anonymous · Answer

and what do I plug into the varaibles @Mertsj

mertsj · Answer

Nothing.  You plug the value for x into the given equation and find the value for y.

anonymous · Answer

Oh, I dont know how you do that, could to show me step by step and I watch?
