How to graph 2 (X+4)^2-6?

Answer 1

Direction: Opens UpVertex: (−4,−6)-4,-6Focus: (−4,−478)-4,-478Axis of Symmetry: x=−4x=-4Directrix: y=−498

Answer 2

You have to choices:

Either you make a table with x and y, and plot the resulting values

Or

You would graph the parent function
$y=x^2$

then:
shift it to the left 4 units
and
shift it down 6 units
and
compress it vertically with factor of 2

I think this would help you.
