f(x)=x/(x+1), D={x in R:x>-1}

(can restrict |h|<(x+1)/2

f(x)=1/sqrt(x-4), D={x in R:x>4}

  • Uniform Continuity : Epsilon-delta Proof of Continuity of f(x) = x ^ (1/3)

    The epsilon-delta definition of continuity is stated as below: A function f from R to R is continuous at a point p R if given > 0 there exists > 0 such that if |p - x| < then |f(p) - f(x)| < .

  • Uniform limit of continuous functions

    Then, we'll have: for the given epsilon>0 we have found delta>0 such that |f(x)-f(c)| <= |fn(x) - f(x)|+|fn(x)-fn(c)|+|fn(c)-f(c)| < epsilon/3 + epsilon/3 + epsilon/3=epsilon and thus the continuity of f(x

  • Functions: Limits

    However, as delta is constrained, |f(x)-f(a+)| quickly meets the condition on epsilon. We could of course choose an even smaller epsilon which would necessitate the choice of even smaller deltas. Hence, the limit exists and has a value of 0.5.
