Question

The major axis, coordinates of the vertex and the focus of the parabola  
         are as follows:

Answer

the major axis is x-axis, the vertex is V  (0, 0), and the focus is  F (2, 0 ).

Answer

the major axis is y-axis, the vertex is V  (0, 0), and the focus is  F (0,  4).

Answer

the major axis is y-axis, the vertex is V  (0, 0), and the focus is  F (0,      ) .

Answer

the major axis is x-axis, the vertex is V  (0, 0), and the focus is  F ( -  1 , 0 ).
