WitrynaIf the function f defined as f(x) = `1/x - (k - 1)/(e^(2x) - 1)` x ≠ 0, is continuous at x = 0, then the ordered pair (k, f(0)) us equal to (3, 1). Explanation: If the function is continuous at x = 0, then `lim_(x rightarrow 0)` f(x) … Witryna12 paź 2015 · It should better be written as. f: R ∖ { 1 } → R, x ↦ f ( x) = x 2 − 1 x − 1. For a function to be continuous at some point c of its domain, it is neccesary for the function to be defined at this point. As f is not well-defined at x = 1, it makes no sense to ask about continuity.

"Witryna5 wrz 2016 · It is continuous at 0. By construction, the domain of the square-root function is R + = [ 0, ∞). Now, for any sequence ( x n) n ∈ N in the domain (that is, x n ≥ 0 for all n ∈ N) that converges to 0, one has that the corresponding function values x n also converge to 0 = 0.

Witryna5 lip 2024 · a) If we want the function to be continuous at x = 1, does that mean that both of the one-sided limits equal to 2? In that case, would I plug in that y-value and a random x-value that satisfies the restrictions to find the possible values of a and b? b) x cannot be -2. x has to be bigger than or equal to -b. WitrynaIn mathematics, a continuous function is a function such that a continuous variation (that is a change without jump) of the argument induces a continuous variation of the value of the function. This means that there are …

WitrynaTake the function f(x)=x² on the interval [-1, 1]. f is continuous on that entire interval, including at the endpoints, but not defined past them. You can also take this function and change the output at the points -1 and 1 only, so that the function is continuous on (-1, 1), discontinuous but still defined at -1 and 1, and undefined elsewhere.
