Question

A parabola has a vertex at (3, -2). What is the axis of symmetry? x = _____

-2


3


-3


2

Answer 1

x = 3.

Explanation:

The equation of the parabola is

f(x) = a(x - 3)^2 - 2 where the vertex is (3, -2).

The axis of symmetry passes though x = 3

Answer 2

x =3

Explanation:

The axis of symmetry is at the vertex

The x coordinate gives the axis of symmetry

x =3
