What are they asking?

The parabola is in position I.

y^2= 4x
x^2= 6y
x^2+ 10y = 0
x/2= y^2
3y = x^2

ok ill try that

anonymous · Answer

but what exactly are they asking for

anonymous · Answer

They gave me partial credit for those 2

anonymous · Answer

see, 
Let S = y^2 =4ax be the equation of the parabola and P(x1,y1) be any pt. in the region of the parabola then
S1= y^2 = 4ax
if S1>0 then p is outside the parabola
if S1 = 0 then P lies on the parabola
if s1<0 then p lies inside the parabola
