Hi, 
Graph 
(y+2)^2=4(1)(x-1)
To 'sketch' the graph, the relationship between x and y described tells us:
   I.  Parabola opening to the right
  II. Vertex is (1,-2)
 III. Focal Point is ((1+1),-2)or (2,-2)and focal chord width = 4   ||  {{{4p = 4}}} & p = 1
  IV. Directrix is x = 0  and Line of symmetry is y = -2
