Best ResponseYou've already chosen the best response.1So I think you mean (x^225)/(x5) right? This expression does not exist at x=5 because when you plug in 5 you get something/0 Now when you have 0/0 that means the limit can exist Is there any algebra you can perform to force a function that is continuous at 5?

Best ResponseYou've already chosen the best response.1yep then plug in 5 to resulting function that is continuous at 5

Best ResponseYou've already chosen the best response.1that isn't how you factor x^225

Best ResponseYou've already chosen the best response.1x^2a^2=(xa)(x+a) you have x^25^2=(x5)(x+5)

Best ResponseYou've already chosen the best response.1right but what do yo notice about the top and bottom (As far as factors go)

Best ResponseYou've already chosen the best response.1and you have (x+5)(x5)/(x5)

Best ResponseYou've already chosen the best response.1right you basically get rid of the discontinuity so you can plug in x=5
