y = x − 4 + 8
Find the xcoordinate of the vertex of
the graph.
And the ycoordinate of the vertex of the graph.
Please help me, I'm stuck!

you have to put it into a vertex form
y=a(xh)^2 +k
y=x+4(because of sign )+8
now you have to get ^2
y=a(.5x2)^2+8
y=1(.5x2)^2+8
now k shifts up or down IE y axis
h shifts left or right IE x axis but a +h=h and a h=+h so your vertex would be (2,8) because h is 2 and k is 8
