Graphing Logarithmic Functions

This algebra video tutorial explains how to graph logarithmic functions using transformations and a data table. It explains how to identify the vertical asymptote as well as the domain and range of the logarithmic function in interval notation.

I appreciate everything you have done for the highschool math community.

[hoomanperson]

Where my "day before the test" gang at!!!

[BenZzBenZzXtremOG_]

Thanks to him I’m getting better at math and I got a 90 this quarter

I would hate to think of how many collective hours I have spent watching your videos throughout high school and college, you are the example of a free market teacher who does it because you like it which in turn means you are probably one of the most effective math teachers ever. I will probably never stop watching your videos.

[Salanghaeo]

You are very easy to understand and explain everything very clearly, unlike my teacher lol. Thank you!

[rutii.a]

It took me 4 hours to understand it by myself 😭😭 but after watching this video I understood it in 12 minutes thank you very much I appreciate ur videos!

[randomnameforarandomnerd]

you and sal khan have been more present in my life than both my parents combined, i love y’all sm

[Alexandra]

Hey you who’s scrolling and feels like you can’t do this... you can do this

[oliverjune]

This is one of the best math videos I've ever seen, I started not knowing what the base of the log was, and now with a little more practice, I could probably teach this.

[aureliusxvincent]

I have never learnt this before, the explanations were well made and easy to follow. Thank you!

[lindseymarie]

this was super helpful, you're awesome at conveying topics in the most efficient ways

MR. Organic Chemistry Tutor, thank you once again for another fantastic video on Graphing Logarithmic Functions.

[Yemane]

this tutor has helped me get a scholorship he is amazing

[annaheetderks]

Oh my goodness this makes SO MUCH SENSE! Thank you so much!

[falayeadeyinka]

Thank you and God bless you and your family. It is deeply insightful!

[ThomasJadallah]

Who else is in a state where they are watching the video yet not taking in any information?

[bobrohubres]

Omg thank you so much man !!! You have been helping me since I started college since I forgot some steps you’re awesome

[arsenhere]

I have a math test tomorrow on logs. I feel as though a giant burden has been lifted off of my shoulders. Thank you kind man.

Log (x) =y is equivalent to 10^y = x. This cannot reflect along the graph y=x if the g(x) = y = 2^x, as they are two entirely different bases and do not reflect. I am also pretty sure that it will only reflect graphically if it has a base of 2. So, instead of Log (x), you have to use Log_2 (x). I hope this problem doesn't get overlooked

You have carried me in math and science for the past 2 years, thanks 😭
