How do you find the axis of symmetry and vertex point of the function: #y=3x^2+3 #?
Axis of symmetry:
Note that any parabolic equation of the general form:
has a vertical axis of symmetry.
is in this general form.
Further, it can be re-written as
which is the vertex form with a vertex at
Its (vertical) axis of symmetry (i.e.
therefore, the axis of symetry is
