Observe the given graph of conic :
The function 
represents a parabola.
The standard form of parabola is 
.
Compare with .
The values of 
.
The vertex is 
and axis is horizontal.
The focus is 2 unite above or below the vertex.
Moreover, p = 2, it follows that the focus lies above the vertex.
The graph of the parabola has been shifted 2 units to the left and 1 unit upward from standard position.
The graph of the parabola is horizontal shift 2 units to the left and vertical shift 1 unit upward from standard position.
