Question 682268: Greetings, I am doing homework on a website.
Here is the problem: Write a quadratic function to model the graph (a graph is provided but is not vital for the tutor to understand my question.).
The coordinates of the vertex are (h,k)= (3,2)
when substituted the values into the equation the equation becomes

Why is h=3 in the ordered pair of the vertex but it is 9 in the vertex form equation?

Answer by MathLover1(20849) (Show Source): You can put this solution on YOUR website!

whoever put it in the vertex form equation is wrong
if you are given the equation
and the vertex at (,)= (,), means that and
then you have , NOT ; here is squared and that is incorrect
