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. WebSep 7, 2024 · We will see that if a function is differentiable at a point, it must be continuous there; however, a function that is continuous at a point need not be differentiable at that point. In fact, a function may be continuous at a point and fail to be differentiable at the point for one of several reasons.

"WebMay 16, 2024 · We will need the definition of continuity which is that: f (x) is continuous at x = a ⇔ lim x→a f (x) = f (a) So, in order to prove that the function defined by: f (x) = xsin( 1 x) Is continuous at x = 0 we must show that lim x→0 xsin( 1 x) = f (0) This leads is to an immediate problem as f (0) is clearly undefined.
