The correct answer for the question shown above is the second option (Option b), and the option cwhich is:
b) x = -1/16y^2
c) y=-1/16x^2
The explanation is shown below:
The focus of a parabola is (h,k+1/4a), then, you have:
h,k= (0,0)
1/4a=1/4(-1/16)
Then, you obtain:
1/4a=-4
Therefore, the focus of the equation of the parabola x = -1/16y^2 and the parabola y=-1/16x^2 <span>is F(0-4)

So, as you can see, the correct answer is the options mentioned before, the option b and the option c.
Can you list the factors of each of those numbers (the numbers that divide evenly into them)? Of those three lists, what's the highest number present in all three?
15 + (6x11) = 81 this is the correct answer to the first one
