Graphs are attached!

Answer 1

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

Answer 2

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

Answer 3

What is a co-ordinate?

Answer 4

a point*

Answer 5

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.

Answer 6

and what do I plug into the varaibles @Mertsj

Answer 7

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

Answer 8

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