Derive the equation of the parabola with a focus at (-2, 4) and a directrix of y = 6. Put the equation in standard form. Of(x) =
fx) = 1x2-x
--X+4
0 1x) = - Ex
--x2-x+ 4
X + 5
O f(x) = 5x2-x+
0) = - x2-x+5
Of(x) =

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
