A function, f(x), has domain 0<< 12 and range -8 < f (2) <4 f(3) = -5
f(7) = 2
Select the statement that must be false about f (2)
A O f (4) = -5
B. O f (6) = -4
C. Of(7) = 5
D. f(10) = 2

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.
