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