What does this mean? By "its axis" do you mean the axis of symmetry? If so does this mean that the axis of symmetryisthe x axis? And what does the (-4, -20) mean?

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 it corect ?
