WebDefinition: A function f is continuous at x0 in its domain if for every ϵ > 0 there is a δ > 0 such that whenever x is in the domain of f and x − x0 δ, we have f (x) − f (x0) ϵ. Again, we say f is continuous if it is continuous at every point in its domain. Is Sinx a continuous function? The function sin (x ) is continuous everywhere. WebMay 19, 2015 · The function f (x) is continuous at point a if and only if the limit lim x→a f (x) exists and equals f (a).

WebJul 9, 2024 · The following function factors as shown: Because the x + 1 cancels, you have a removable discontinuity at x = –1 (you'd see a hole in the graph there, not an asymptote). But the x – 6 didn't cancel in the denominator, so you have a nonremovable discontinuity at x = 6. This discontinuity creates a vertical asymptote in the graph at x = 6. WebAccording to this, a function is continuous if and only if f (x) as x approaches a = f (a). But what if we have a piecewise function, like, g (x) = {3x, x does not equal 2} {-10, x = 2 } • ( 7 …
