Question

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!

Answer 1

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
