Which of the following functions has a vertex of (-4,3) and a line of symmetry of x= -4? O A. f(x) = 2(x +4)2 – 3
OB. f (x) = 2(x - 4)2 + 4
O c. f (x) = 2(x +4)2 + 3
OD. f (x) = 2(x - 3)2 + 4
E. f (x) = 2(x – 4)2 + 3

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.

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
