Standard equation of parabola -

y^{2}=4ax

- wherein

 

 y^{2}= 4(x-1)

y^{2}= -4(x-3)

y^{2}= 4(3-x)


Option 1)

y2= 4(3-x)

This solution is incorrect

Option 2)

y2 = 4x - 4

This solution is incorrect

Option 3)

both (a) and (b)

This solution is correct

Option 4)

none of these

This solution is incorrect
