One-Sided Limits Go to Infinity

For more videos visit problemsolvedm...
This Math Help Video Tutorial is all about how to solve one-sided limits that go to infinity by plugging in numbers near the limit’s x-value. What do you do when a limit from one side gives zero in the denominator?

**Who is Matt Groden?**
Hey there! I'm Matt. I make videos that make math click for students.
The energy in my videos comes from my love for math and teaching. I am grateful to have spent over 10 years teaching in a public high school and middle school in Southeast, Pennsylvania. I loved coming into class every day to teach everything from Algebra 1 to those who struggle with math through to teaching AP Calculus AB and BC to those who love math and everyone in between. I thought to bring the many inspiring lessons and moments I was fortunate my students and I shared together to the world with these videos.
So here I am making videos for you whether you are learning basic math in middle school all the way up through advanced levels of Calculus in college. I am driven to help you to see math does not need to be difficult. I want to pull you into the screen with me so you can see how math connects. And, of course, I am here to help you understand the difficult concepts so you can get homework help, study for tests, and get better grades with these math video tutorials.

I don't see a lot of these specific limit problems so this was very helpful. Thank you!

i dont get how the top one is infinity/-negative infinity and the bottom one is not infinity but an actual value to the limit? really stumped with this

[@problemsolvedmathtutoring883]

Thanks for your question. Can you please specify which problem you are referring to at a specific minute mark of the video? Thanks! Hope all is well.

⁠​⁠​⁠​⁠​⁠​⁠​⁠​⁠​⁠​⁠​⁠​⁠@@problemsolvedmathtutoring883I think we’re referring to (first set of problems x approaching -1). So if you plug in the number x is approaching and it has a 0 in the denominator, it’s automatically infinity?

@@softycat9737 ​ thanks so much for clarifying! Yes, as long as the numerator is not zero and the denominator is zero, the limit will approach positive or negative infinity. Thanks for watching! Check out all my Calculus videos on my channel! Be well😊
