How does the graph of y is equal to A times open paren x minus h close paren squared plus 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 to (2h, k), so its horizontal distance from the y-axis doubles. Therefore, the correct choice is “The vertex of the graph moves to a point twice as far from the y-axis.”
