But, lim x-> x0+ f(x) ≠ f(x 0) (Because we have filled circle at different place). Hence the given function is not continuous at the point x = x 0.. Question 2 : … WebThe asymptote is for g(x) while the function f(x) crosses the asymptote. g(x) approaches the asymptote from the right side but never touches it. In fact, it does not matter whether asymptote is vertical, slant, or horizontal. No function will cross its own asymptote. tl wdn5200h 驱动

WebIf you really have $f(0,0)=1$, then it is easy to see that the function is not continuous, because the limit---if it exists---will have to be zero. This can be seen as suggested by … WebOne is to check the continuity of f (x) at x=3, and the other is to check whether f (x) is differentiable there. First, check that at x=3, f (x) is continuous. It's easy to see that the limit from the left and right sides are both equal to 9, and f (3) = 9. Next, consider differentiability at x=3. This means checking that the limit from the ...
