Answer:
x = 2
Step-by-step explanation:
The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves.
The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
You already know the vertex, so the axis of symmetry is the line, x = 2.
This is because the equation to graph a vertical line is x = a, where a is the x-value you want the line to intersect.
