Question

The vertex of a parabola is (-1, 4). What is the equation of the axis of symmetry of the parabola?

Answer 1

x=-1

Explanation:

Parabola is symmetric on both sides of the vertex

The axis of symmetry is the x coordinate of vertex

Here the vertex is (-1,4)

So axis of symmetry is x=-1

Answer 2

• x = - 1

Explanation:

The vertex is given (-1, 4).

The axis of symmetry is a vertical line and passes through vertex.

Since the x- coordinate of vertex is - 1, the line of symmetry is x = - 1.
