Question

what is the equation for the axis of symmetry?
options: x=5, x=1, y=3, x=3

Explanation:

The axis of symmetry of a vertical parabola is a vertical line \(x = h\), where \(h\) is the x-coordinate of the vertex. Looking at the graph, the vertex (lowest point) of the parabola lies on the vertical line \(x=1\).

Answer:

B. x=1
