Use a graphing utility to graph the function. Then use the trace or table feature to identify the limit.
lim 5/x2 x>2
I know I posted this question before but I am still having a hard time doing this. I pressed the y= button and typed the normal equation in: 5/x2. Is this correct and if so now what do I do?

Exactly what you do depends on your calculator. Check your manual, or you might find it online. You need to graph, then use the trace function to approach the limit and see what the function does.
