ALGEBRA2 HELP PLEEEASE! identify the maximum or minimum value and the domain and range of the graph of the function y=2(x-3)^2 -4

OpenStudy (mertsj):

What is the vertex?

OpenStudy (anonymous):

I dont know :(

OpenStudy (anonymous):

(6,-4)? \

OpenStudy (mertsj):

\[y=a(x-h)^2+k\] Vertex is (h,k)

OpenStudy (anonymous):

OH! so (-3,4)?

OpenStudy (mertsj):

(3,-4)

OpenStudy (anonymous):

-4 sorry

OpenStudy (mertsj):

Domain is all real numbers. Range is y>=-4

OpenStudy (mertsj):

Since this parabola is concave upward, the vertex is the minimum point.

OpenStudy (anonymous):

thank you so much!
