Find the equation of the parabola with its focus at (0,-4) and its directrix y = 4. .O A) y=-1/gx²
B) y=1/1072
OC) y = -1/16x²
OD) y = -1/4X²

Which simplifys to a+ b? a-(1-b)+1 -(1-a)-b+1 (a--1) -1)+1

Write an equation for the function that includes the points (1,4/5) and (2,2/3)

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0
