@Loser66 can you help explain the problem?

11. Loser66

from $$y =\sqrt{x}$$, we have $$x =y^2$$ and the vertex is (0,0) , the graph is |dw:1437603450677:dw|

12. Loser66

now, the vertex form is $$x =a (y-k)^2+h$$ , from the given one, we have a =1, h, k are given, just plug in!!

13. Loser66

Remember, if y = x^2 , then the vertex form is y = a(x-h)^2 +k, but this problem gives us x =y^2, hence the location of h, k on vertex form are exchanged.
