The standard form of a parabola with its axis parallel to x-axis is:
%28y-k%29%5E2=4p%28x-h%29
Its vertex is (h, k)
*********************************************************************
SOLUTION:
Re-write the equation in standard form:
%28y-1%29%5E2=4%2A1%2A%28x-0%29
So h = 0, k = 1
Thus the vertex is (0, 1).
