1. The problem statement, all variables and given/known data Let f be the function such that f(x)=1+^2 if x is irrational and f(x)=1+4x^4 if x is rational. Use the Squeeze Theorem to find (lim x->0)f(x). Clearly, for all real numbers x, f(x)>=1. Next, we note that for a real number x, x^2−4x^4=(x^2)(1−4x^2)>=0 if and only if ? >=0. This means that x^2>=4x^4 if and only if x [?,?] 3. The attempt at a solution I've been stuck on this question for a while.any hints to start me off?
