Determine whether f is continuous at 0
WebOct 10, 2014 · Explanation: Alternative definition number 1. Let f:X → Y be a function and let (xn) be a sequence in X converging to an element x in X, ie lim (xn) = x ∈ X. Then f is continuous at x iff and only if the sequence of function values converge to the image of x undr f, ie ⇔ lim (f (xn)) = f (x) ∈ Y. Alternative definition number 2. WebDec 28, 2024 · To determine if \(f\) is continuous at \((0,0)\), we need to compare \(\lim\limits_{(x,y)\to (0,0)} f(x,y)\) to \(f(0,0)\). Applying the definition of \(f\), we see that …
