Derive the equation of the parabola with a focus at (2, −1) and a directrix of y = −one half. f(x) = −(x + 2)2 − three fourths f(x) = (x + 2)2 + three fourths f(x) = −(x − 2)2 + three fourths f(x) = −(x − 2)2 − three fourths

Okay would you like steps or just a straight answer?

@supercalifragalisticexspeaalli I guess you gave up on Slader.

@Hero Please do not bring trouble thank you for the notification but if u look alot of other people they give straight answer. Also, i was just about to explain how i got the answer.

okay as i was saying we are trying to find the vertex

To be specific the vertex form of a parabola

yea

The equation for this is y = a(x - h)^2 + k

OpenStudy (supercalifragalisticexspeaalli):

k

OpenStudy (xhawaiiangirlx):

(h, k) is the vertex but in this case it is (2,-1)

OpenStudy (supercalifragalisticexspeaalli):

k

(2,-1) is the focus, not the vertex @XhawaiiangirlX

OpenStudy (xhawaiiangirlx):

(2,-1) is the vertex and focus inn this equation hero thx for pointing that out :)
