SOLUTION:
We are to find the equation that best represents the axis of symmetry in the given graph.
The axis of symmetry is the line that divides the graph into two equal parts and it is parallel to y - axis.
By critical and careful examination, it is clear that the line of symmetry is x = 2 ( when you draw a line parallel to y-axis, it divides the graph into equal parts.
So the correct option is G that is, x = 2
