These are very simple & conept testing problems, try to solve them.

1) A certain funcion f(x)is contious and attains only rational value
  and f(0)= 3, then roots of the equation f(1)x^2+f(3)x+f(5)=0 are of what
nature?

2) Find fof(x) for f(x)= x...if x is rational
                         1-x...if x is irrational.

3)1111.....(91 digits)..1, prove that it not a prime number.

4)Find the values of "a" for which sin^4x + cos^4x = a.

5)Solve for x, x[x]-x^2-3[x]+3x>0       ... {[x] represents greatest
                                          integer not greater than x.}
