Assignment:
Proof that f is continuous for each x in D in accordance with the epsilon-delta defitinition of continuity(can use the defintion involving f(x+h)
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}
(can restrict |h|<(x-4)/2
Provide complete and step by step solution for the question and show calculations and use formulas.
