WebJan 26, 2024 · The function f (x) = x sin (1/x) is continuous everywhere except at x = 0, where it has a removable discontinuity. If the function is extended appropriately to be continuous at x = 0, is it then differentiable at x = 0 ? The function f (x) = x 2 sin (1/x) has a removable discontinuity at x = 0. WebIf f ( x) and g ( x) are continuous at some point p, and g ( p) ≠ 0, then f ( x) g ( x) is continuous at p. Then you put together the parts. For example, 1 x is continuous …

WebJul 18, 2015 · Each of the 4 functions is continuous on the interval on which it is used: 3x − 1, x2 +1, and x − 4 are polynomials, hence continuous everywhere. 5 x − 2 is discontinuous at 2, but it is not used near 2, so that is not a problem. We need to check for continuity at the numbers 2, 7, and 9. WebAt x = c ≠ 0, the function is continuous. This post proves it. Notice that the δ they find depends on the value of c. And that the smaller c is, the smaller δ must be to ensure that the output of the function jumps no more than ε. If this doesn't make intuitive sense, think about the graph of f (x) = 1/x near 0.
