NettetUsing L'Hopital's rule again! lim x->inf (2x/e^x) = lim x->inf (2/e^x) = 2/inf = 0 ... Well, as x approaches infinity-- 5 divided by infinity-- this term is going to be 0. Super duper infinitely large denominator, this is going to be 0. That is going to approach 0. And same argument. This right here is going to approach 0. NettetI solved the limit as x approaches infinity of that given function using a change of variable in order to make use of L'Hopital's rule. By direct evaluation, we get an indeterminate form... Nettet2. des. 2024 · The three examples above give us some timesaving rules for taking the limit as x x approaches infinity for rational functions: If the degree of the numerator is less than the degree of the denominator, then \lim_ {x\to\infty} f (x) = 0 limx→∞ f (x) = 0. If the degree of the numerator equals the degree of the denominator, then red light blinking on motion detector light
