I have a problem with this question: What is the vertex of the parabola with the equation y = 2(x + 4)2 + 8?
Could someone explain it to me? Thank you!
Plot the function - where is the "minimum" of the graph?

Go to:

and you'll see that when the equation of the parabola is expressed as:
y = A(x-b)2 + h
then the vertex of the parabola is at (b, h)

Just another way to look at it: For this problem, the definition of vertex is the place where y is the smallest [had it been a -2, it would have been where it were the largest]. Since 2(x + 4)2 is always positive or zero what is the smallest it can be? What would x then be? What then would y be?
