    Hey people!
    I'm studying maths at uni and someone just asked me to find the limit of the following function as x tends to 0.
    My first thought was that it had an asymptote at x=0 since the function has a 5x^2 at the bottom and as x tends to 0 the function goes off to infinity. However apparently the limit is -0.1. I've graphed it on wolframalpha.com and it does indeed cross the y-axis at -0.1. Am i just missing something really trivial or what? Help please

    Look up L'Hopitals rule.

    Basically you look at the differentials of the top and bottom, if otherwise you would have 0/0
Have you ever experienced racism/sexism at uni?
