Find the equaion of the parabola having its vertex at the origin , its axis as indicated :
A ) x-axis : (-4, - 20 )
b) y - axis : (30,-15 )
C) y - axis : (-root2,3)
my answer
A )
we have (-4, - 20 ) that mean the focus ( - 20 , 0 )
now we do comper 4ay = - 20
= -5
then the equation is : y2 = 4ax
= y2 =4(-5) x
=y2 = -20 x
----------------
I sove only number one beacuse i am not sure from my answer
help me Are this solving corect or not ?
