WebYes. It can be. Here is an example that I faced in one of my works. Assume X to be an Exponential distribution ( f X ( x) = e − x) and Y = 1 X. For this case, E ( Y) = ∞ . Indeed, writing the expectation as integral: E ( Y) = ∫ 0 ∞ 1 x e − x d x. you see that the integral diverges at the lower bound.

However, there are cases where a function can be bounded, but still have no limit, like the limit as x goes to 0 of sin (1/x). So by saying 'unbounded', we are conveying not only that the limit doesn't exist, but the the function exhibits a certain behavior. iowa marriage index 1800s

"WebThe first is by factoring the denomiator: lim x → 1 x − 1 ( x − 1) ( x + 3) = lim x → 1 1 x + 3 = 1 4. The second is by using L'Hospital's rule, which is a useful identity in limits.
