 Sep24 awarded Autobiographer Apr7 accepted Is limits $\lim_{x\to\infty}{(x-2)^2\over2x+1}=\dfrac{1}{2}$? Apr7 comment Is limits $\lim_{x\to\infty}{(x-2)^2\over2x+1}=\dfrac{1}{2}$? @DanielFischer are you going to write it as an answer? Apr7 comment Is limits $\lim_{x\to\infty}{(x-2)^2\over2x+1}=\dfrac{1}{2}$? What do you mean? I divided both numerator and dneominator by x Apr7 asked Is limits $\lim_{x\to\infty}{(x-2)^2\over2x+1}=\dfrac{1}{2}$? Apr4 accepted Solve this simple polynomial Apr3 comment Solve this simple polynomial @RecklessReckoner Thank you so much, I'll look into synthetic division! Apr3 comment Solve this simple polynomial @RecklessReckoner So how do you come up with $(x^2+x+1)$? Apr3 comment Solve this simple polynomial What do you mean by long division? Do you mean $x^3-x^2-x-2 \over (x-2)$ Apr3 comment Solve this simple polynomial @MichaelHardy My brain is extremely fuzzy right now it's 2 am lol --cramming for exam Apr3 comment Solve this simple polynomial I don't get it. How can you know x-2 is a factor? And if you know it's a factor, how can you come up with x^2+x+1 Apr3 comment Solve this simple polynomial The limit problem holds little relevance to the question Apr3 comment Solve this simple polynomial It is clear, I'm only trying to figure out how I can factor out the problem so that I could obtain x-2 Apr3 comment Solve this simple polynomial @IanColey well, if I got (x-2). I could eliminate them. I'm trying to solve a limit problem Apr3 asked Solve this simple polynomial Mar3 accepted Is a function still a function if it doesn't have any rule? Mar3 comment Is a function still a function if it doesn't have any rule? Ok then never mind the sources, a consensus has been reached. A function it is then. Can someone write the answer? Mar3 awarded Commentator Mar3 comment Is a function still a function if it doesn't have any rule? @ploosu2 for example: f(x)=3+2x. I don't know whether or not it's called a rule though lol Mar3 comment Is a function still a function if it doesn't have any rule? @Emin Why? Can you cite any source?
