Pre-Calculus Lesson 4.1 part1

I am setting the stage for introducing exponential and logarithmic functions by revisiting inverse functions. This is a sample of what we do at FMI. I am nervous being on camera and I am sure math teachers can pick up a few mis-spoken terms. Beyond that, I hope to help shed light on the troublesome section called, "logarithms".

@MegaCheezyWeezy Sweet Dreams!

My school is so lame, I am in integrated Alg. 2 instead of CP Alg 2(4 chapter difference) - but I have a high A in the class, and they won't let me move up to CP Analysis(Precalc) next year.

@ion5061

I teach Pre-Calculus online.

i like, but I cannot see numbers very well...

@glowingdarkmatter25

You are right about the difficulty of seeing the numbers. It was one of my early videos and I had not gotten the hang of how to improve lighting. But I was excited about getting the lesson out on youtube because I thought it would help.

i'm skippin' school today 'cause i don't wanna take a precalc test. i would be taking it right now if i were there

[mistorm]

be my math teacher.

Wow so fucking genius fuck you old nigger you smart you opened my eyes to the door.

@themathmaster How much does that cost?

[TrevorKingKwong]

Is there any practical purpose to comparing a function and its inverse, or are they only useful as separate functions to find a single result such as distance? For example, the only practical purpose I find for comparing the two functions is to compare slopes. So if x = time, and f(x) = distance, this means that according to your graph; the amount of distance covered over time [f(x)/x] is greater than the amount of time covered over the distance [x/f(x)], yes?

@glowingdarkmatter25 okay will keep watching anyway. ;+)
