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
1x...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^23[x]+3x>0 ... {[x] represents greatest
integer not greater than x.}
