The axis of symmetry for a quadratic function is always a vertical line running through the vertex. Since the vertex of this particular function lies at (-3,-2), the axis of symmetry must be the vertical line x = -2.

The axis of symmetry is x=-3

its x= -3
but u shud specify which type of curve this is:
is it
y^2=4ax type --- axis of symmetry y=0
or
x^2=4ay --------axis of symm x=0

It's the vertical line x = -3.

the parabola is symmetrical about this line.
