y = |x − 4| + 8

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!

  • Math -

    you 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
