Hi. I'm confused about calculating the limit of a function involving Euler's number. I need to know the proper way to find the limit so I can determine the equation of the horizontal asymptote of the function. I do know, in my head what the graph looks like so I know that there is a horizontal asymptote is y=0. I just have to show my work, thats where I'm stuck. Here is the problem: lim(x->infinity)(2e^x) My attempt: lim(x->infinity)(2e^x) = lim(x->infinity)(2/e^-x) =lim(x->infinity)(2/e^-infinity) =lim(x->infinity)(2/0) =0 Therefore: y=0 I'm not sure if I'm doing the problem the right way. If I did somehow get it right, can someone please give me a brief description on the proper method? Thanks In Advance.
