PLEASE HELP :) What is the range of the graph y=(x-4)^2+6.

OpenStudy (anonymous):

HINT: the graph of the equation is exactly like y=x^2 but translated 4 units to the right, 6 units up.

OpenStudy (anonymous):

okay, i dont know how to right that though. i dont know how to solve for the range

OpenStudy (anonymous):

someone please help. this is a live homework assignment and im timed and dont know how to reply to this

First, you have to figure out what the vertex is

OpenStudy (anonymous):

your parabola is written in vertex form: \(\large y=a(x-h)^2+k \) where (h, k) is your vertex.

OpenStudy (anonymous):

okay so -4 and 6, how do i get the range from that

hero (hero):

Actually its (h,k) = (4,6)

OpenStudy (anonymous):

ok

Now all you have to do is figure out if the graph is concave up or concave down.
