Algebra 2
Hey I am working on math homework that involves "Standard Form to Vertex Form by Averaging." My class is just starting to learn this today, but I am totally lost still on what to do. Can you please help? The formula for this is y=a(x  h)^2 + k
the h is the xvalue vertex and the k is the yvalue vertex.
I got the first one done and it looks like this:
y=x^2 + 2x +3
1(x^2  2x  3)
1(x + 1)(x  3)
x= 1 and 3
y=(1)^2 + 2(1) + 3
y=1 + 2 + 3
y= 4
then
h=1 and k=4
I have many other like this but this was the only one i understood. If any one knows this process i'd be so thankful for some help! Thank you!
