Quadratic functions q and w are graphed on the same coordinate grid. The vertex of the
graph of g is 18 units below the vertex of the graph of w. Which pair of functions could have
been used to create the graphs of q ankim?
A g(x) = 18x and w(x) = x2
B g(x) = x2 + 18 and w(x) = x2
C 9(x) = -187+ and w(x) = x?
D 9(x) = x? - 18 and w(x) = x2
