Ans 46:(C) Odd no of roots
Solution: f(a)f(b)<0 means
either f(a)>0 and f(b)<0
or f(a)<0 and f(b)>0
means f(a)/f(b) or f(b)/f(a) changes sign from +ve to -ve .
In between at some point f(x)=0 and that point will give you the solution.
It may happen that f(x) cuts x-axis at 1,3,5 and so on points.
So there are odd number of roots.
Ans 47:(A) FSM
Ans 48:(B) 4
Solution: Cardinality of set=16
Number of elements in each equivalence class=4
total number of equivalence classes: 16/4=4
