The General Equation of Parabola having vertex at (0,0) and Focus(a,0) and (0,a) is
[tex]y^{2}= 4ax[/tex] or [tex]x^2 =4ay[/tex]
Now ,the Given equation of parabola having vertex at (0,3) is
x^2=y-3
It is 3 unit above y axis. So the parabola will open in the upward direction.
Out of all the options provided which are
1.y = (x - 3) ^2
2.y = (x + 3) ^2
3.y = x ^2 - 3
4.y = x^ 2 + 3
Option 4. y = x^ 2 + 3 is correct.
