Question

Look at this graph:
What is the equation of the axis of symmetry?

Answer 1

`x = -1`

Explanation:

The axis of symmetry of a graphed quadratic function is a vertical line that passes through the vertex and divides the parabola into two symmetric parts.

The equation of the axis of symmetry of a quadratic function is x = h, where h is the x-coordinate of the vertex.

From observation of the graphed function, the vertex is located at (-1, 1). Therefore, the equation of the axis of symmetry is:

`\Large\boxed{\boxed{x = -1}}`
