If f(x) is continuous on [1,4] and f(1) = 10, f(4)=3 and k =15, then which statement(s) would be true regarding a c value in [1,4] where f(c)=15?
a. a c is not guaranteed to exist.
b. at least one c is guaranteed to exist.
c. there is one c value.
d. there are no c values.
e. there could be one c value.
f. there could be multiple c values.

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.
