f(x) = 3.2^n-1

f(x) = 2x4 ^n-1

f(x) = 2x6^n-1

Step-by-step explanation:

1)

f(1) = 3x2^(1-1)

     = 3x1

     = 3

f(2)= 3x2^n-1

     = 3x2 ^(2-1)

     = 3x2

     = 6

f(3)= 3x2^(3-1)

     = 3x2^2

     = 3x4

    = 12

f(1) = 2x4^(1-1)  

    = 2x1

    = 2

f(2) = 2x4^(2-1)  

      = 2x4

      = 8

f(3) = 2x4^(3-1)

      = 2x4^2

      = 2.16

       = 32

        = 2x6 ^(1-1)

        = 2x1

        = 2

f(2) = 2x6^(2-1)

       = 2x6

       = 12

f(3) = 2x6^(3-1)

    = 2x6^2

    = 2x36

    = 72

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.
