Hi everyone, I'm doing Problems Set for revision in section 1D on limits and discontinuity 1D3 a) (x2)/(x^24) is not simplified for the purpose of finding points of discontinuity; but later on in section 1G Higher Derivatives 1G1 d) (x^2+5x)/(x+5) in the process of finding y' should be consider x=5 as a point of removable discontinuity? Thanks!

Yes because x = 5 is an asymptote. So when the function reaches 5, it's slope will reach infinite. I hope I understood your question correctly.

Thanks, but I don't think x=5 is an asymptote: (x^2+5x)/(x+5)=x What I'd like to know is if there is any rules on when one can simplify an improper fraction.
