Derive the equation of the parabola with a focus at (0, −4) and a directrix of y = 4. (2 points)



f(x) = −16x2
f(x) = 16x2
f(x) = − one sixteenth x2
f(x) = one sixteenth x2

Answer 3

I cant help you with thi I don't know it sorry :(

Answer 4

@santaslitllehelper14 No problem

Answer 5

you can eliminate a couple answers by plugging in x=0 and y=-4 into all the equations in the answer choice.

Answer 6

For example, for f(x) = −16x^2, if you plug in x=0 and y=-4, the equation is -4=-16(0)^2, which is not valid. So you know that is for sure not the right answer.
