oh okay I see where I made my mistake, I have to watch out for whether it goes downward or upward

If you can check this last one since I am worried because I did not get that other one correct

The focus of a parabola is (0,−2) . The directrix of the parabola is the line y=−3

.

What is the equation of the parabola?

y=−1/2x^2−52

y=1/2x^2−52

y=1/4x^2−2

y=−1/4x^2+2

i think it would be option B

I have this one and jsut 1  more if can double check for me I understand if you cant

The directrix of a parabola is the line y=7 . The focus of the parabola is (2,3)

.

What is the equation of the parabola?

y=−1/8(x−2)^2−5

y=−1/8(x−2)^2+5

y=1/8(x−2)^2+5

y=1/8(x−2)^2−5

i think it is option c

The one above is the steps I took as well thank you .

The one where you went over each step more in depth

From your explantation in the other question it really helped ! Thank you

this one if you can also

The directrix of a parabola is y=−8 . The focus of the parabola is  (−2,−6)

.

What is the equation of the parabola?

y=−1/8(x+2)^2+7

y=1/4(x+2)^2−7

y=1/8(x−2)^2−7

y=−1/4(x−2)^2−7

i think it is option 2

Its okay

This one actually ended up being incorrect

I dont see how it wouldve been negatitive. I am sorry  I guess I am not quite getting it. because -1/2 + 1= 1/2
