HELP! Please ALGEBRA SUCKS! Which function has a minimum at -2 and a line of symmetry at x = 3?

A) y = -2x^2 - 12x - 20
B) y = -2x^2 + 12x - 20
C) y = 2x^2 + 12x + 16
D) y = 2x^2 - 12x + 16

Oh and all absurd answer will be reported( •_•), really important test. Best BRAINLEST!

Thanks! (\• v •/)

b

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
