Log functions are kind of cool in that they force us to think backwards. Logarithms are inverses of exponentials (which I covered in this exponential functions video) so when we create our parent table we're thinking y first, then x. This can get a little confusing, so I wanted to make a video to go along with the free logs cheat sheet I posted a while ago on my blog (and that I re-linked here). I'm slowly going through all of the free math cheat sheets on my blog and making videos, which I hope will be helpful if you are ever not able to teach students face-to-face. My hope is that these videos will work for flipped classrooms, on remote learning days or even as an extra support.

In this post is a video and a free graphing log functions cheat sheet. The cheat sheet can be given to students for their notebooks or enlarged to create an anchor chart (link to directions on how to do this easily is below).

Here is a step-by-step video on how to graph log functions by first creating a parent table and then shifting this table and plotting the shifted points.

Here is the basic parent table that we can use to graph any log function.

And here is a link to the free graphing logarithm functions cheat sheet. This is the sheet I refer to in the video. The steps on the sheet are the same steps I walk through in the video.
