An ordered pair and a line are given. The ordered pair belongs to a quadratic function whose graph is symmetric about the given line. Find another ordered pair of this function. A) (2,3); x=1

1. The given point is (2, 3) and the line of symmetry is x = 1.
2. In a quadratic function, points that are symmetric with respect to a vertical line have the same y-coordinate.
3. Since the line of symmetry is x = 1 and the given point is (2, 3), reflect the x-coordinate of the given point over the line of symmetry.
4. The distance from the given point to the line x = 1 is 2 - 1 = 1.
5. Reflecting across x = 1 gives a new x-coordinate of 1 - 1 = 0.
6. Therefore, the new point is (0, 3).

[Solution]

(0, 3)
