1. The problem statement, all variables and given/known data
Evaluate the limit or show it doesn't exist. (x→∞) lim ((x+2)/√x) where (x > 0) 2. Relevant equations 3. The attempt at a solution I know how to solve it if x → c but i don't know how to start it when it goes to infinity. I just need a hint as to how to start the problem.

so after evaluating, i found that the limit does not exists... am i correct? work: ((x+2)/√x)/1  Does not exist since the numerator is always bigger than the denominator x→∞, x > o

Please get me started on showing that the following limit exists[itex]\displaystyle\frac{a + b}{c} = \frac{a}{c} + \frac{b}{c}[/itex].

Also, because x is approaching infinity, you don't need to say that x > 0.

The one you're thinking of is f(x) = (1)^{x}. Without parentheses, what you wrote is the same as (1^{x}).

Thank you. I think i understand now.
