Graphing logarithmic equations

👉 Learn all about graphing logarithmic functions. A logarithmic function is a function with logarithms in them. The graph of the parent function of a logarithmic function usually takes its domain from the positive x-axis. To graph a logarithmic function, it is usually useful to first graph the parent function (without transformations). This can be done by choosing 2-3 points from the function and plotting them on the x-y coordinate axis to see the nature of the parent function's graph.
After graphing the parent function, we then apply the given transformations to obtain the required graph. When a constant is added to x in the function, the graph of the parent function shifts to the left by the same units as the constant added to x. Similarly, when a constant is subtracted from x in the function, the graph of the parent function shifts to the right by the same units as the constant subtracted from x.
When a constant is added to the function, the graph of the parent function shifts upwards by the same units as the constant added to the function. Similarly, when a constant is subtracted from the function, the graph of the parent function shifts downwards by the same units as the constant subtracted from the function.

i was confused at first about this concept(day before test) and now it's so easy to understand. Thanks!

[akm]

Oh yeah yeah I'm going to pass my algebra 2 test now

[genuinelyright]

THANK YOU SOOOO MUCH AND ALWAYS MR.McLogan, you absolutely saved my pre cal grades and I’m a senior at high school, this means so much to me, thanks for your hard working and these wonderful exact tutorials... from the bottom of my heart.

[memeheadquarters]

This man is a legend, props to him for saving my math grade so many times!

[liliacfury]

I don’t know why all math teachers don’t do this. Just record your sessions and post it and you have the possibility of getting even more money from YouTube views (which I assume many teachers would appreciate since they are payed shit money)

[roronoa]

isn't the point supposed to be (4, -4) and not (-4, -4)? but anyways, i have always been watching you thank you for saving my grades!

[klabushnell]

Very straight forward, and easy to understand. Thank you!

[alil]

I have an Acedemic Decathlon math packet of algebra and trig. I'm doing it right now, also having to finish up a speech, science, art, and music packet so I'm hurrying. Just skippedy hoppedy past the 10 page introduction and explanations of new topics I haven't even done before and watch your videos for help. Extremely helpful and effect. Thanks you!

[vedanttiwary]

I have my final tommorow and this was so helpful. Only if my teacher were like you!

[aaronl]

Appreciate the help! These videos really do make my courses easier.

[JackHoleey]

2:20, u went 6 points to the right since u count the first one as 1.. u were like 1, 1 2 3 4 5.. Anyways, great video, thank you

[angelmejia]

Here in 2021 and he is rocking, explains so smoth in a really short time

[tababyto]

Thank u so much for this....unlike other tutorials...u clearly explained every details of graphing logarithm

[jzzo_official]

Bless you so much sir, may god have a special place in heaven reserved for you, you cleared my head so much THANKYOU

[joselopezjr.]

Thank you! I love your math videos. God bless.

[poptropicabob]

My teacher showed us the long way. Nobody had time for all that so this way is pretty useful!

[isaacsmith]

Thankyou so muck. Im an 9th grader in algebra 2, and I was really struggling before your videos.

[RenuGupta-jkjw]

You are great. Thanks a lot for such helpful videos.

[Cirrustudio]

BLESS YOUR HEART this cleared everything

What do I do with: f(x)=3 log base 2 (x-1) ??? I know what the 3 in front of the log means, but what do I do with it after the other transformations??
