In the notation "s(x) = " what does "s(x)" represent?
a. the value of x depends on the value of sex), since x is a function of s.
b.
the value of s(x) depends on the value of x, since s is a function of x.
c.
the value found whien sis multiplied by the value x.
d.
there is not enough information to answer this question.

a) 7x=7

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.
