Watching math videos on RU-vid is less confusing, wordy, quick, and frustrating than a school/secondary institution lecture, now that's guaranteed (most of the time).
Where were you 2 years ago!!! Omgosh! I would have only taken my precalc class once instead of 3 times!!! Thank God I found you now! I actually have a chance of passing. And it's the last class that I need to get my AA and transfer to CSULA. Thank you, Thank you, THANK YOU!!!! I will be having my sons learn from you as well and am gladly subscribing. :))
I absolutely would love for you to teach my calculus class. I come home after calculus each week feeling like...what the heck did I just learn???? Then I look up your videos and I am saved on exam day. Thank you so much.
Good evening professor. I am 26 years old. I am married with four children, a Marine and will eventually progress to medical school. I have concluded that everyone needs a math professor like you. I am open to you adopting me as your own child. Kidding! That was an enjoyable video though............................P.S. Seriously though. Consider the offer.
I do not understand why 1 elevated to the Xth powers should be excluded from the set of exponential functions, even if you let "a" go down from a number bigger than one to a positive number smaller than 1 nothing special happens, except for he fact that 1 elevated to the xth power is a straight horizontal line. Why should this horizontal line not be a member of the set of exponential functions?
You're wrong when u say the base can't be negative. The base can be negative. x is independent variables y is dependent variables. y = (-2)^x for example. If I give 2 as the value of x so y = (-2)^2 so y = -2 x -2 , y = 4
any base raise to any power either positive or negative the answer is always positive. bases must be positive when evaluating exponential and logarithmic functions. just like square root you can't take the roots of negatives.
