Quadratic functions g(x) and h(x) are graphed on the same coordinate grid. The vertex of the graph of h(x) is 12 units above the vertex of the graph of g(x) . Which pair of functions could have been used to create the graphs of g(x) and h(x) h(x)=x2−18 and g(x)=x2

h(x)=x2+18 and g(x)=x2

h(x)=(x−18)2 and g(x)=x2

h(x)=(x+18)2 and g(x)=x2
