How does the graph of y = a(x – h)2 + k change if the value of h is doubled?

In vertex form, y = a(x − h)² + k, the vertex is (h, k). Doubling h changes the vertex’s x-coordinate from h to 2h, while its y-coordinate k stays the same. Thus, the vertex moves to a point twice as far from the y-axis, so the correct choice is B.
