Recall that a real number is rational if it can expressed as a number - where a and b are integers and b # 0. A b 1+ 2x2 if xis rational real number is considered irrational if it is not rational. Consider the function f (x) = if x is irrational Use the squeeze theorem to show that lim f (x ) =1. (Hint: Consider the behavior of values of x which are x->0 within 1 unit from 0)
