Quadratic functions g(x) and h(x) are graphed on the same coordinate grid. The vertex of the grid of h(x) is 12 units above the vertex of graph g(x). Which pair of functions could have been used to create the graphs of g(x) and h(x)? A. h(x)=x^2−12 and g(x) = x^2
B. h(x)=(x+12)^2 and g(x) = x^2
C. h(x)=x^2+12 and g(x) = x^2
D. h(x)=(x−12)^2 and g(x) = x^2
