Using a directrix of y = 2 and a focus of (3, −4), what quadratic function is created? f(x) = one twelfth (x − 3)2 − 1 f(x) = −one sixth (x + 3)2 + 1 f(x) = one sixth (x − 3)2 + 1 f(x) = −one twelfth (x − 3)2 − 1

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

explanation:

remove parenthesis:
