4 Which ordered pairs do not belong to a linear function in the form below?
y = kx + b
O A. (0, 1); (1, 0); (2, -1)
O B. (0, 1); (1, 2); (2,5)
OC. (-2,5); (-1, 2); (0, -1)
OD. (-2, 1); (-1, 1); (0, 1)

I think the answer is C...

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.
