How to Write Equation of Logarithmic Function From Graph MHF4U Pre Calculus

Important steps to write the equation from the graph of logarithmic function are discussed in the video.
• What are Logarithms?
Properties of Logarithms with Proof
• Write exponential equations in logarithmic forms
• Evaluate each logarithms
• Evaluate common logarithms
• Evaluate natural logarithms
Logarithms are inverse of exponential functions. Converting logs to exponential forms helps to evaluate or solve equations. Rules of logarithms can be applied to simplify expressions. Simple approach in the video helps to understand the basic concepts.
Logarithmic rule for change of base can be applied to simplify expressions with different basses as shown in the video with many examples.

His voice alone completly removes the stress I had about this topic

[LJ-mloz]

this guy did better explaining the same topic in 8 min than my teacher did for the past week

This video is 5 years old, but it's the only one that has helped me. Bless you sir!!

[aibbincubus]

Thank You-Thank You-Thank You-Thank You-Thank You!!!!

[stadricklenageiki]

I really like your explanations, it's helping me in some of my problems on writing equation on logrithmic function
Thanks...😍😍👍🙏✍

[dashkajulien]

well done and well made thank you. i really love your pens.

How to find the stretch and compression factors

[feniislandgurl]

Thank you very much Sir, your videos have helped me a lot. 🙏

[benlang]

Thank you!! Very helpful, you explained it MUCH better than my sucky math teacher, you just gained a new subscriber

[ff_m]

Can you do an example with the Vertical and Horizontal compression/expansion and with the Vertical translation? Like the whole transformed function? Thanks though it really helped me.

[oreofe]

this was an amazing explanation that made understanding it so much easier! Thank you so much

How would you work this out if you do not have the x-intercept?

[lucaw]

great explanation, but what would I do if I wasn't given an intercept, just 2 other points?

[kantovagrant]

How would we find logarithmic functions from just points themselves?

[swarudiys]

Sir, if you are only given one point can you still determine the equation? Or only give a set of values for each variable?

[maxpeters]

What do you do if say, the graph was reflected over the x axis and shifted up, making the known point have a Y value of 0? You end up with a^0 = (some value) and idk what to do from there
