The line of symmetry is the line that goes through the vertex of this parabola. Do you know how to find the vertex?

no

Your equation is already given in what is called "vertex form". Given:\[y=a(x-h)^2+k\]The vertex is the point (h,k).

Ohhh! Okay got it!

So, what's the vertex?

And remember that once you have the vertex, you still need to find the line of symmetry.

-2?

x=-2 is correct. Saying "-2" doesn't tell us anything. Make sure you write x=-2. This is a vertical line through the point (-2,-4). It cuts the parabola into symmetry halves. It is the line of symmetry for this parabola. Make sense?
