Find the x-coordinate of the vertex of

the graph.

And the y-coordinate of the vertex of the graph.

Please help me, I'm stuck!

**paul**, Thursday, November 4, 2010 at 12:35amyou have to put it into a vertex form

y=a(x-h)^2 +k

y=x+4(because of sign ||)+8

now you have to get ^2

y=a(.5x-2)^2+8

y=1(.5x-2)^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
