y = x2 + 14x + 21; a = 1, b = 14, c = 21
x-coordinate = -b/2a = -14/2 = -7
if it is y = x2 + 14 + 21, the x-coordinate is zero, since b = 0.

What is the vertex of y equals x-3 plus 2?
The equation is linear and so has no vertex.
What is y equals x2 plus 2x plus 1 on a graph?
Interpreting that function as y=x2+2x+1, the graph of this function would be a parabola that opens upward. It would be equivalent to y=(x+1)2. Its vertex would be at (-1,0) and this vertex would be the parabola's only zero.
